• Does BizSpark preclude you from accepting funding elsewhere?

  - by Clay Shannon

  I am going to embark very soon on a software venture (have been a consultant and employee up until now). I see advantages in signing up for Microsoft's BizSpark. However, I wonder if doing so would preclude me from accepting funding from some equity-esque arrangements potentially available via crowdfunding. I know BizSpark's legal agreement probably spells this out, but it's about a gazillion pages long, so I'm hoping somebody here has existing knowledge of this so I don't have to spend a lot of time reading legalese.

• using egrep to find missing @ in log

  - by jols

  I am using the following command to find log entries that are the result of a log in to the email server: egrep '_login[^ ]' /var/log/exim_mainlog That works fine to find entries that contain content like this: P=esmtpa A=courier_login:[email protected] S=1573 id=f1cd08396,... But what I need to do is to change my grep statement, so that it finds single word logins that do not use the @ sign, like so: P=esmtpa A=courier_login:name S=1573 id=f1cd08396,... Where the log in before was "[email protected]", but in the second log entry, the log in used was only "name". Is this possible using grep or egrep, perhaps in some kind of a compound statement? Thanks much.

• Why is sudo bash different from regular bash

  - by cyberjar09

  Problem description : I am using something called play framework in my development which requires me to make the python script play available in the path. Hence I create a symbolic link in /usr/local/bin ... Now I have written a shell script (call it status.sh) which calls this python script as follows : play status <some values here related to my app> &> /tmp/xyz.txt and this shell script then sends me the file via email. This works perfectly when I execute the script as follows ./script.sh. However when the script is executed as a cron expression everyday I get an output from stderr saying 'play: command not found'. Hence I did some digging on my own and here are my findings : echo $PATH when I am on the shell shows that I have /usr/local/bin available to me hence I can successfully execute the command play status however when I type in sudo bash and then echo $PATH I do not have the path /usr/local/bin anymore. It is a limited set of folders (one of them being /usr/bin). Q : Why this behavior ?! I fail to understand why the path is different. Also as a workaround would you suggest I do : new symbolic link from /usr/bin to /usr/local/bin (what are the side effects of this?) remove /usr/local/bin sym link altogether and only use /usr/bin is there a convention that I am not following here for linking new programs and executing them from $PATH ? Thanks.

• How to emulate Fn (function key) keypress in xte

  - by komputes

  xte is part of the xautomation package. After hours of man page reading and looking for documentation or working examples, I still cannot get xte to emulate a Fn-F7 keypress. xte 'keydown Meta_L' 'key F7' 'keyup Meta_L' I've tried Meta_L, Meta_R, Multi_key, key F7, keydown F7 then keyup F7. No combination seems to work. Any idea how I can emulate a combination key press with a Fn key from a command/script?

• passing a font as an argument to a script

  - by josinalvo

  I am trying to use osdSH for notifications. It has a 'font' parameter that receives a curiously formed string. From the man: -f -font Set font (Default: -*-lucidatypewriter- bold-*-*-*-*-240-*-*-*-*-*-*) The manual does not comment on the arguments passed (I assume each * represents a possible argument). It would seem that this notation is (or has someday been) standard, but I've not been able to find anything about it. what is the standard ? what argument specifies letter size ?

• rc.local is not always executed upon boot

  - by starcorn

  Hey, I have some weird problem with the rc.local file which is located in /etc/rc.local the thing is that it is not always running when I boot up the laptop. Maybe every second time, I haven't counted. Anyway when that happens I have to manually go to terminal and type sudo /etc/init.d/rc.local start, which kinda kills the purpose of having this script. Anyone know what the problem could be? EDIT Since this wasn't obvious. This is an issue where I make a fresh boot up. Which mean I have shut down the computer. And next time when I boot up the computer, the rc.local file is randomly deciding whether it will automatically start or not. Here's a copy of what my rc.local file contains echo -n 255 > /sys/devices/platform/i8042/serio1/serio2/sensitivity echo level 2 > /proc/acpi/ibm/fan touch /home/starcorn/Desktop/foo rfkill block bluetooth exit 0

• Bash script won't stay open in background after running through while

  - by jfreak53

  I can't get the following bash script to stay open after the first message is received from NC: #!/bin/bash port=3333 nc -l $port | while read msg; do notify-send Alert "$msg"; done After the first message it exits. I want it to stay open and continue monitoring for new messages from NC. I know that if I launch nc -l port without the while loop it stays open and I can chat away between the two connections even disconnect from the connected host. I am sending the message using: echo 'done' | nc IP port

• The Exceptional EXCEPT clause

  - by steveh99999

  Ok, I exaggerate, but it can be useful… I came across some ‘poorly-written’ stored procedures on a SQL server recently, that were using sp_xml_preparedocument. Unfortunately these procs were  not properly removing the memory allocated to XML structures – ie they were not subsequently calling sp_xml_removedocument… I needed a quick way of identifying on the server how many stored procedures this affected.. Here’s what I used.. EXEC sp_msforeachdb 'USE ? SELECT DB_NAME(),OBJECT_NAME(s1.id) FROM syscomments s1 WHERE [text] LIKE ''%sp_xml_preparedocument%'' EXCEPT SELECT DB_NAME(),OBJECT_NAME(s2.id) FROM syscomments s2 WHERE [text] LIKE ''%sp_xml_removedocument%'' ‘ There’s three nice features about the code above… 1. It uses sp_msforeachdb. There’s a nice blog on this statement here 2. It uses the EXCEPT clause.  So in the above query I get all the procedures which include the sp_xml_preparedocument string, but by using the EXCEPT clause I remove all the procedures which contain sp_xml_removedocument.  Read more about EXCEPT here 3. It can be used to quickly identify incorrect usage of sp_xml_preparedocument. Read more about this here The above query isn’t perfect – I’m not properly parsing the SQL text to ignore comments for example - but for the quick analysis I needed to perform, it was just the job…

• Script to recursively grep data from certain files in the directory

  - by Jude

  I am making a simple shell script which will minimize the time I spend in searching all directories under a parent directory and grep some things inside some files. Here's my script. #!/bin/sh MainDir=/var/opt/database/1227-1239/ cd "$MainDir" for dir in $(ls); do grep -i "STAGE,te_start_seq Starting" "$dir"/his_file | tail -1 >> /home/xtee/sst-logs.out if [ -f "$dir"/sysconfig.out]; then grep -A 1 "Drive Model" "$dir"/sysconfig.out | tail -1 >> /home/xtee/sst-logs.out else grep -m 1 "Physical memory size" "$dir"/node0/setupsys.out | tail -1 >> /home/xtee/sst-logs.out fi done The script is supposed to grep the string STAGE,te_start_seq Starting under the file his_file then dump it sst-logs.out which it does. My problem though is the part in the if statement. The script should check the current directory for sysconfig.out, grep drive model and dump it to sst-logs.out if it exists, otherwise, change directory to node0 then grep physical memory size from setupsys.out and dump it to sst-logs.out. My problem is, it seems the if then else statement seems not to work as it doesn`t dump any data at all but if i execute grep manually, i do have data. What is wrong with my shell script? Is there any more efficient way in doing this?

• How do I change Firefox's `about:config` from a shell script?

  - by James Haigh

  On of the first things I do when first using a fresh Firefox profile, is to set browser.urlbar.trimURLs to false (which really should be changeable though ‘Preferences’ or should have remained default), and to change the search and homepage defaults to DuckDuckGo. Currently I manually go to about:config, click through the angry warning message, and search for the keys (which unlike in DConf Editor, aren't even organised). So I would like to know how to read and write these keys from the command-line so that I can add these tweaks to my customisations script.

• starting project with growth in mind.

  - by marabutt

  I have an idea for a web application and have some good people keen to get involved. I will be doing most of the code at the start and have a few years experience with some quite large projects. I have nearly 0 budget. What view should I take with regard to data storage / database? Get the project running quickly and inexpensively, then re-evaluate if it is a success? Does anyone have experience with this and advice?

• How can I delay dropbox from starting, but not disable it?

  - by jgbelacqua

  When I log into my user account on Ubuntu 10.10, there is a unsatisfying delay before my system becomes usable. Even launching a terminal, I have to wait a few seconds before the bash prompt appears. During this start-up period, the top process seems to be dropbox. I'm not sure what it's doing exactly (functionality is still fine as far as I can see), but I do know it really doesn't need to be doing it while I'm waiting for desktop to appear. (This is the standard Ubuntu with Gnome desktop, by the way.) What I would like to do is to be able to have a static or even dependency-based delay for dropbox to start. It would be nice if it waited for, e.g., 10 minutes, or for my browser tabs to load and a typing pause. Then it could churn away on file status or cache-chewing, and I would be happy. Is there a way to do this? Thanks!

• Auto-Invoke Update Manager to update everything and shutdown after system idle for x minutes?

  - by unknownthreat

  I have Ubuntu 10.10 installed on a machine for my parents. The thing is they never request updates from Update Manager even the manager itself prompted them so. Moreover, when they are done with whatever they are doing on Ubuntu, they always leave the computer on. And I always have to come back and shut the machine down. Sometimes, the computer even sit idle for hours. So I want to know whether this is possible in Ubuntu. I am thinking of a script that will be activated after the machine is idle for x minutes. When x minutes have elapsed, Update Manager will automatically update everything listed. (I recall that you need the admin password for this, so is there a workaround?) After all the updates are done, the machine will automatically shutdown. Is this possible?

• Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

  - by Al Rowe

  Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

• Volume setting isn't remembered after restart/shutdown

  - by Iulian

  This is my first time here and I'm new to linux and also to Ubuntu. I've installed first version 11.10 and there was some problems with the unity dock and also the problem with the volume not being remembered after restart or shutdown. I'm using dualboot with Windows 7. Ubuntu was installed after windows. I have 2 sound cards. One is onboard, on the motherboard, and the other is external, an E-MU 0404 USB 2.0 sound card. The last one is my primary sound card and I've choosed it as default output sound card. I've upgraded to 12.04 hopeing that this was fiex but even in this version the OS doesn't keep the volume where it was last time. The big problem is that sometimes I forget about this problem and start music and it starts at full volume and soon I think I will die of heart attack. Is there a way to make it remember or at least to tell him to start at a specific volume not at 100%?

• Transmission shutdown script for multiple torrents?

  - by Khurshid Alam

  I have written a shutdown script for transmission. Transmission calls the script after a torrent download finishes. The script runs perfectly on my machine (Ubuntu 11.04 & 12.04). #!/bin/bash sleep 300s # default display on current host DISPLAY=:0.0 # find out if monitor is on. Default timeout can be configured from screensaver/Power configuration. STATUS=`xset -display $DISPLAY -q | grep 'Monitor'` echo $STATUS if [ "$STATUS" == " Monitor is On" ] ### Then check if its still downloading a torrent. Couldn't figure out how.(May be) by monitoring network downstream activity? then notify-send "Downloads Complete" "Exiting transmisssion now" pkill transmission else notify-send "Downloads Complete" "Shutting Down Computer" dbus-send --session --type=method_call --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.RequestShutdown fi exit 0 The problem is that when I'm downloading more than one file, when the first one finishes, transmission executes the script. I would like to do that but after all downloads are completed. I want to put a 2nd check ( right after monitor check) if it is still downloading another torrent. Is there any way to do this?

• Script / App to unRAR files, and only delete the archives which were sucessfully expanded.

  - by Jeremy

  I have a cron job which runs a script to unrar all files in a certain directory (/rared for argument's sake) and place the expanded files in /unrared. I would like to change this script so that it deletes the original rar archives from /rared only if they successfully extracted. This does not mean that unrar has reported that they have been fully extracted, because I have had data corruption during decompression before. Ideally (pie-in-the-sky, just to give you an idea of what I'm shooting for,) the unrar program would include this functionality, comparing an expected md5sum value with the actual md5sum value and only deleting the archive if they match. I don't mind scripting this entire process if I have to, but there must be a better way than unraring twice and comparing md5sums.

• Database Backup History From MSDB in a pivot table

  - by steveh99999

  I knocked up a nice little query to display backup history for each database in a pivot table format.I wanted to display the most recent full, differential, and transaction log backup for each database. Here's the SQL :-WITH backupCTE AS (SELECT name, recovery_model_desc, d AS 'Last Full Backup', i AS 'Last Differential Backup', l AS 'Last Tlog Backup' FROM ( SELECT db.name, db.recovery_model_desc,type, backup_finish_date FROM master.sys.databases db LEFT OUTER JOIN msdb.dbo.backupset a ON a.database_name = db.name WHERE db.state_desc = 'ONLINE' ) AS Sourcetable   PIVOT (MAX (backup_finish_date) FOR type IN (D,I,L) ) AS MostRecentBackup ) SELECT * FROM backupCTE Gives output such as this :-  With this query, I can then build up some straightforward queries to ensure backups are scheduled and running as expected -For example, the following logic can be used ;-  - WHERE [Last Full Backup] IS NULL) - ie database has never been backed up.. - WHERE [Last Tlog Backup] < DATEDIFF(mm,GETDATE(),-60) AND recovery_model_desc <> 'SIMPLE') - transction log not backed up in last 60 minutes. - WHERE [Last Full Backup] < DATEDIFF(dd,GETDATE(),-1) AND [Last Differential Backup] < [Last Full Backup]) -- no backup in last day.- WHERE [Last Differential Backup] < DATEDIFF(dd,GETDATE(),-1) AND [Last Full Backup] < DATEDIFF(dd,GETDATE(),-8) ) -- no differential backup in last day when last full backup is over 8 days old.

• Find Column in All Databases

  Occasionally, there comes a requirement to search all databases on a particular server for either columns with a specific name, or columns relating to a specific subject. In the most recent case, I had to find all similar columns in all databases because the company plans to change the datatype of these columns. [...]

• Contract-Popup at Login

  - by Steve

  I want to give my notebook to guests of my little Hotel as an extra service. I love the Ubuntu guest-account and I think that this is the best possible way to help my guests get free internet-access. I found out how to "design" their user-accounts with /etc/skel, but unfortunately I have no clue, how to show them a small introduction to the system and a kind of user-agreement "contract" when they login. I read of xmessage, but this is too minimalistic. I'd like to implement some pictures. Does anyone have any idea of how to make this possible? Would it be possible that the user is logged out automatically if he rejects the user-agreement? Thank you so much in advance, Steve.

• Select (loop) or command not working in shell-script

  - by user208098

  I've been tinkering with Linux and Unix for years but still a novice in my mind and recently find myself trying to be more pro with it as I work in IT. So with that notion I'm studying shell scripting. I've hit a snag in ubuntu using the latest version 13.10 Saucy. When I use the select command in a sh script it doesn't work, depending on how I format the command it will either return Unexpected "do" or Unexpected "done". See the following two examples: This section of code produces an unexpected "do" error: #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit do case $opt in "option1") echo "you chose choice 1" ;; "option2") echo "you chose choice 2" ;; "option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done This section of code produces an unexpected "done" error. #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit ; do case $opt in "Option1") echo "you chose choice 1" ;; "Option2") echo "you chose choice 2" ;; "Option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done When I enter these parameters into the command line interactively or manually I get the desired result which is a list of choices to choose from. However when executed from a script I get the before mentioned errors. Also a side note I have tried this in Fedora as a script and it worked perfectly so my question is why isn't it working in Ubuntu, is this a difference between RHL and Debian? Or is it a bug in the latest version of Ubuntu? Thanks in advance for any help! KG

• Fail to start windows after Ubuntu 11.10 install

  - by user49995

  Computer: HP Pavilion dv7-6140eo OS: Originally Win7 I recently decided to try out Ubuntu, and I decided to dual-boot it with Windows 7. First I googled some how-to's, then I downloaded Ubuntu onto a memory stick and made a second partition (I originally only had one partition that I shrunk and used the unallocated space to install onto during the Ubuntu install). During the install I set format type to xt4 (or something, it was the default option), chose the "in the beginning" option and set the last option as "\". The install was successful. Although, when I restarted my computer I weren't able to choose which operating system to start; it went right into windows. After showing the windows logo for half a second before rebooting, I get a blue screen (see bottom of the page). Trying to fix it, I deleted the newly made partition I had just installed Ubuntu onto (seeing it wasn't working either). This made no difference. I proceeded with installing Ubuntu again, so I would at least have a functioning computer, and now Ubuntu works fine (on it now). The only difference on start-up is that I get a Grub window asking me to between several options including Linux and Windows 7 (loader). Now, if I choose Windows 7, I get the message "Windows was unable to start. A recent software or hardware change might be the cause". It recommends me to choose the first option of the two it provides; to start start-up repair tool. The second option being starting windows normally. If I start windows normally, the same thing happens as earlier. My computer does not have a windows installation CD. Although, it has (at least it used to, if I haven't screwed that too up) a 17gb recovery partition. In addition I made an image of the computer onto a external hard drive when I first got it. Though, I have no idea how to use either. If anyone has any idea how I can make windows work again or reinstall it (already backed up my files) it would be greatly appreciated. I still prefer to dual boot between the two functioning operating systems, but I will settle for a functioning windows 7. Thanks a lot for any replies. Blue screen: A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps: Check for viruses on your computer. Remove and newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configures and terminated. Run CMKDSK /F to check for hard drive corruption, and then restart your computer.
