• Shell - How to find directory of some command?

  - by Gabriel L. Oliveira

  I know that when you are on shell, the only commands that can be used are the ones that can be found on some directory set on PATH. Even I don't know how to see what dirs are on my PATH variable (and this is another good question that could be answered), what I'd like to know is: I come to shell and write: $ lshw I want to know a command on shell that can tell me WHERE this command is located. In other words, where this "executable file" is located? Something like: $ location lshw /usr/bin Anyone?

• Partial Upload With storbinary in python

  - by brian

  I've written some python code to download an image using urllib.urlopen().read() and then upload it to an FTP site using ftplib.FTP().storbinary() but I'm having a problem. Sometimes the image file is only partially uploaded, so I get images with the bottom 20% or so cut off. I've checked the locally downloaded version and I have successfully downloaded the entire image, which leads me to believe that it is a problem with storbinary. I believe I am opening and closing all of the files correctly. Does anyone have any clues as to why I'm getting a partial upload with storbinary? Update: When I run through the commands in the Python shell, the upload completes successfully, I don't know why it would be different from when run as a script...

• Correct way to give users access to additional schemas in Oracle

  - by Jacob

  I have two users Bob and Alice in Oracle, both created by running the following commands as sysdba from sqlplus: create user $blah identified by $password; grant resource, connect, create view to $blah; I want Bob to have complete access to Alice's schema (that is, all tables), but I'm not sure what grant to run, and whether to run it as sysdba or as Alice. Happy to hear about any good pointers to reference material as well -- don't seem to be able to get a good answer to this from either the Internet or "Oracle Database 10g The Complete Reference", which is sitting on my desk.

• cannot read but can write on serial port through Android Emulator

  - by Aad

  I am working on a program that is communicating with serial port over USB through Android emulator. emulator -qemu -serial /dev/ttyUSB0 The emulator is able to open the port and write into it. However, read is not happening. The program has a timeout for read maintained by a timer. The read happens in a separate 'read' thread. The main thread has a socketpair fd pair to signal the read-thread that the serial port is closed post timeout. In the read-thread, polling happens(poll() function call) over the 2 file-descriptors: one is serial port fd, the other is one of the socketpair. The board that I have connected to works fine with sending commands over 'cutecom' The poll never succeeds for serial port. However, poll succeeds for 'socketpair'ed fd and the thread ends on a close-signal sent from main-thread post timeout. Ouestions: Are there any special settings for read as even loop-back fails Are there differences between settings for read and write on a serial port?

• Recursive wildcards in Rake?

  - by Roger Lipscombe

  Follow up to this question about GNU make: I've got a directory, flac, containing .FLAC files. I've got a corresponding directory, mp3 containing MP3 files. If a FLAC file is newer than the corresponding MP3 file (or the corresponding MP3 file doesn't exist), then I want to run a bunch of commands to convert the FLAC file to an MP3 file, and copy the tags across. The kicker: I need to search the flac directory recursively, and create corresponding subdirectories in the mp3 directory. The directories and files can have spaces in the names, and are named in UTF-8. It turns out that this won't work in make, because of the spaces in the directories and filenames, so I'm wondering how to do it in rake instead...

• how to use execute() in groovy to run any command

  - by drake

  I usually build my project using these two commands from command line (dos) G:\> cd c: C:\> cd c:\my\directory\where\ant\exists C:\my\directory\where\ant\exists> ant -Mysystem ... ..... build successful What If I want to do the above from groovy instead? groovy has execute() method but following does not work for me: def cd_command = "cd c:" def proc = cd_command.execute() proc.waitFor() it gives error: Caught: java.io.IOException: Cannot run program "cd": CreateProcess error=2, The system cannot find the file specified at ant_groovy.run(ant_groovy.groovy:2)

• Resharper 5 - enable/disable on the fly

  - by Cristi Diaconescu

  I want to disable ReSharper 5 when debugging - it slows things down more than I'm willing to take. Is there an automatic way to do this? The next best thing would be a toolbar button to manually enable/disable it. On the Tools - Options - ReSharper page there's a comment that the VS command Resharper_ToggleSuspended would do just this. The problem is, I can't find the command when I right-click a toolbar - Customize... - 'Commands' tab - Choose 'Resharper' category. Am I missing something?

• ruby1.9.1 can't find installed gems, yet ruby1.8 can...

  - by Zombies

  On ubuntu here. I installed both ruby1.8 and ruby1.9.1. I also ran these commands ruby1.8 setup.rb ruby1.9.1 setup.rb Both worked fine, I was also able to install gems for both. The gems in gem 1.9.1 and gem1.8 both show up correctly for gem list. The problems however begin with this: ruby1.9.1 some_script.rb. It cannot find any of the gems. I tried uncommenting some out figuring that parseconfig was the problem, yet it couldn't find any of the others, which are definetly in gem1.9.1 list. Any thoughts as to what is causing this/how to recover?

• multiple FileSystemWatchers to monitor files on local system?

  - by Jason Crowes

  We're writing a text editor like tool for our internal accounting package system that has actions that can be done by our own Xml language specs. These macro commands are specified in Xml files and we need the ability to monitor if files openned have bean modified externally. The only problem is that there maybe 20-30 files with different paths openned at any one time. Would it be good to use multiple FileSystemWatchers for this scenario? Or would it be better to monitor the root drive and catch specific events that match an open file in the editor (though lots of events could be raised). Some are local drives (C,D,E) others are their network drives (U,X,G,H). Files are quite chunky too about 300-400Kb.

• How can you set a time limit for a PowerShell script to run for?

  - by calrain

  I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I have looked at background jobs but they operate in a different thread so won't have kill rights over the parent thread. Has anyone dealt with this or have a solution? Thanks!

• cd Terminal at a given directory after running a Python script?

  - by Dave Everitt

  I'm working on a simple Python script that can use subprocess and/or os to execute some commands, which is working fine. However, when the script exits I'd like to cd the actual Terminal (in this case OS X) so on exit, the new files are ready to use in the directory where the have been created. All the following (subprocess.Popen, os.system, os.chdir) can do what I want from within the script (i.e. they execute stuff in the target directory) but on exit leave the Terminal at the script's own directory, not the target directory. I'd like to avoid writing a shell script to temporary file just to achieve this, if this is at all possible anyway?

• How to create digital signature that can not be used to reproduce the message twice

  - by freediver

  I am creating a client-server application and I'd like to send data from server to client securely. Using public/private key algorithms makes sense and in PHP we can use openssl_sign and openssl_verify functions to check that the data came by someone who has the private key. Now imagine that one of the actions sent by server to client is destructive in nature. If somebody uses an HTTP sniffer to catch this command (which will be signed properly) how can I further protect the communication to ensure that only commands coming from our server get processed by the client? I was thinking about using current UTC time as part of the encrypted data but client time might be off. Is there a simple solution to the problem?

• Why does jQuery do this in its constructor function implementation?

  - by mattcodes

  If we look at the latest jQuery source at http://code.jquery.com/jquery-latest.js we see the following: var jQuery = function( selector, context ) { // The jQuery object is actually just the init constructor 'enhanced' return new jQuery.fn.init( selector, context ); } My understanding of the new keyword in Javascript is essentially JavaScript passes the function an empty object {} and the function sets stuff on it via this.blah. Also from my understanding new differs from .call/.apply etc.. in that the return object also has the prototype set to that of the function. So the return value should have a prototype that the same as jQuery.prototype.init.prototype (or jQuery.fn.init.prototype). However from what I see its prototype is set to jQuery.prototype thus all the commands available to work on the set. Why is this? What am I missing in my understanding?

• Which Maven Glassfish plugin to use?

  - by Nick Klauer

  I've been trying to integrate deploying java .war's in Glassfish V3 through Maven. While I have found a few plugins, none of them look to be very active: Maven Glassfish Plugin Eskato's Wordpress Blog on Maven And I got the most information out of Eskato's Blog, it was written March 2008, so I don't know what the state of Glassfish Maven integration is, nor can I find a suitable plugin to work with. With the Maven Glassfish Plugin I have had some success, but it still doesn't work entirely well for all goals it says it supports, which makes some of the commands ineffective. Has anyone else been able to integrate Glassfish V3 and Maven successfully? If so, what resources did you use to get it done?

• How to tell process id within Python

  - by R S

  Hey, I am working with a cluster system over linux (www.mosix.org) that allows me to run jobs and have the system run them on different computers. Jobs are run like so: mosrun ls & This will naturally create the process and run it on the background, returning the process id, like so: [1] 29199 Later it will return. I am writing a Python infrastructure that would run jobs and control them. For that I want to run jobs using the mosrun program as above, and save the process ID of the spawned process (29199 in this case). This naturally cannot be done using os.system or commands.getoutput, as the printed ID is not what the process prints to output... Any clues? Edit: Since the python script is only meant to initially run the script, the scripts need to run longer than the python shell. I guess it means the mosrun process cannot be the script's "son process". Any suggestions? Thanks

• Why is distributed source control considered harder?

  - by Will Robertson

  It seems rather common (around here, at least) for people to recommend SVN to newcomers to source control because it's "easier" than one of the distributed options. As a very casual user of SVN before switching to Git for many of my projects, I found this to be not the case at all. It is conceptually easier to set up a DCVS repository with git init (or whichever), without the problem of having to set up an external repository in the case of SVN. And the base functionality between SVN, Git, Mercurial, Bazaar all use essentially identical commands to commit, view diffs, and so on. Which is all a newcomer is really going to be doing. The small difference in the way Git requires changes to be explicitly added before they're committed, as opposed to SVN's "commit everything" policy, is conceptually simple and, unless I'm mistaken, not even an issue when using Mercurial or Bazaar. So why is SVN considered easier? I would argue that this is simply not true.

• Bash loop command until file contains n duplicate entries (lines)

  - by Andrew

  Hello, I'm writing a script and I need to create a loop that will execute same commands until file does contain a specified number of duplicate entries. For example, with each loop I will echo random string to file results. And I want loop to stop when there are 10 lines of of the same string. I thought of something like while [ `some command here (maybe using uniq)` -lt 10 ] do command1 command2 command3 done Do you have any idea how can this problem be solved? Using grep can't be done since I don't know what string I need to look for. Thank you for your suggestions.

• Django equivalent to paster for backend processes

  - by intractelicious

  I use pylons in my job, but I'm new to django. I'm making an rss filtering application, and so I'd like to have two backend processes that run on a schedule: one to crawl rss feeds for each user, and another to determine relevance of individual posts relative to users' past preferences. In pylons, I'd just write paster commands to update the db with that data. Is there an equivalent in django? EG is there a way to run the equivalent of python manage.py shell in a non-interactive mode?

• C# Running several tasks at different intervals

  - by Nir

  A design question: I'd like to build a Windows service that executes different commands at different intervals. For simplicity's sake, let's say I want to run some batch files. The input it gets is a list of files and the intervals at which to execute. For example: a.bat - 4 minutes b.bat - 1 minute c.bat - 1 minute d.bat - 2 minutes I was thinking about sorting them according to intervals, and then setting a timer for each of the intervals. I'm not sure this is the best solution and I'd be happy to hear some feedbacks. Thanks!

• How do I dynamically specify a file in DOS?

  I am trying to use c# in .net to run dos commands to ftp a a file. Technically, it calls a BAT file which calls a CMD file which executes the DOS code. It was up to the CMD file. The CMD fiel will work if I hardcode the path, but I need to dynamically specify the path of the file. BAT File... ftp.exe -s:%~dp0\mycmdfile.cmd And in the cmd file... open <my ost> <my user name> <my pw> quote site cyl pri=1 sec=1 lrecl=1786 blksize=0 recfm=fb retpd=30 put <here is where I need the dynamic path> + localfilename remotefilename quit

• Self hosted WCF console output from service

  - by user989056

  quick one: Is it possible to capture the output stream of a WCF service that is hosted via ServiceHost ( self hosted service) ? I have methods within my WCF service that output useful debugging information, is it possible to send these to it's host's console output? Edit: It appears that I have made an obvious blunder - I was using Debug instead of Console. It is possible to output to the console by using the standard Console output commands in your WCF service class. I have marked the answer that I have found the most useful.

• Making archive from files with same names in different directories

  - by Tim

  Hi, I have some files with same names but under different directories. For example, path1/filea, path1/fileb, path2/filea, path2/fileb,.... What is the best way to make the files into an archive? Under these directories, there are other files that I don't want to make into the archive. Off the top of my head, I think of using Bash, probably ar, tar and other commands, but am not sure how exactly to do it. Renaming the files seems to make the file names a little complicated. I tend to keep the directory structure inside the archive. Or I might be wrong. Other ideas are welcome! Thanks and regards!
