  • bash disable line wrap without truncation

    - by Eric Huang
    I am using a template heavy library in c++ and need to understand the template errors. Reading line wrapped template errors is a serious pain. Is there a way to disable line wrapping in bash without also truncating the output. Additionally, is there a way to do horizontal scrolling on the output. I have seen this answer, how to make bash not to wrap output?, but the output is truncated. The solution doesn't have to be bash targeted, if there is method for this using another shell, tmux, piping make output to another program, compiling from within vim, etc, I'll use it. (Except for copy-pasting into gedit)

  • How can I allow a linux subversion user to only execute svnserve?

    - by sbleon
    I've got a user that I'd like to only be able to use subversion. We like to use svn+ssh:// URLs sometimes (for public keys and whatnot), so I need them to be able to connect over ssh and run only the svnserve command. When using a svn+ssh URL, svn ssh'es in and passes the arguments "-c svnserve -t". I wrote a custom shell as follows to filter the commands that can be run. This works, but it's not passing the input to svnserve, so when I try to "svn up" I get "svn: Connection closed unexpectedly". #!/bin/bash if [ "$1" == "-c" ] && [ "$2" == "svnserve" ] && [ "$3" == "-t" ] && [ "$4" == ""] ; then exec svnserve -t else echo "Access denied. User may only run svnserve." fi

  • How do I give MacPorts privileges?

    - by cojadate
    I tried to install PostgreSQL server development libraries using MacPorts and got the following: Warning: MacPorts running without privileges. You may be unable to complete certain actions (e.g. install). ---> Computing dependencies for postgresql-server-devel ---> Dependencies to be installed: postgresql-devel ---> Building postgresql-devel Error: Target org.macports.build returned: shell command failed Error: The following dependencies failed to build: postgresql-devel Error: Status 1 encountered during processing. To report a bug, see <http://guide.macports.org/#project.tickets> So I guess that means I need to running MacPorts with privileges and try again. Unfortunately I've no idea how to give MacPorts privileges. I'm running OS X 10.6.3

  • Cygwin/Git Bizarre Terminal Issue

    - by emptyset
    Alright, this is weird. First off, this is mintty running on up-to-date cygwin, with git pulled from cygwin's setup.exe. I am running zsh. $ git clone https://<user>@<domain>/<repository>/ ~/src/project/dev Initialized empty Git repository in /cygdrive/c/src/project/dev/.git/ Password: <actual password in plain text appears> # Nothing happens... ^C $ <password text that I just typed> zsh: command not found: <same password text> What is going on here? Is this a terminal problem, a shell problem, a git problem, or a cygwin problem? Update: Yes, I'm running the Cygwin git version, not the Windows version: $ which git /usr/bin/git $ git --version git version 1.7.1 $ /cygdrive/c/Program\ Files\ \(x86\)/Git/bin/git.exe --version git version 1.7.0.2.msysgit.0

  • How to associate the ".exe" extension to be opened with Mono?

    - by wuser
    I want to asssociate the .exe file extension to Mono (don't care about wine). Apparently, when using Finder's GUI, only .app files (application bundles) can be selected. But the Mono executable (/Libraries/Frameworks/Mono.Framework/Current/bin/mono) is no such bundle. I tried some AppleScript on run this_file do shell script "mono this_file &" end run but Finder's GUI still doesn't allow to associate that with .exe's. How to associate a specific file extension to a command-line application in Mac OS X?

  • Sort and display directory list alphabetically using opendir() in php

    - by felixthehat
    Hi there, php noob here - I've cobbled together this script to display a list of images from a folder with opendir, but I can't work out how (or where) to sort the array alphabetically <?php // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n";} } closedir($handle); } ?> Any advice or pointers would be much appreciated!

  • Sane(r) way to get character-encoding of CLI?

    - by danyowdee
    Hi all! I was writing a CLI-Tool for Mac OS X (10.5+) that has to deal with command-line arguments which are very likely to contain non-ASCII characters. For further processing, I convert these arguments using +[NSString stringWithCString:encoding:]. My problem is, that I couldn't find good information on how to determine the character-encoding used by the shell in which said cli-tool is running in. What I came up with as a solution is the following: NSDictionary *environment = [[NSProcessInfo processInfo] environment]; NSString *ianaName = [[environment objectForKey:@"LANG"] pathExtension]; NSStringEncoding encoding = CFStringConvertEncodingToNSStringEncoding( CFStringConvertIANACharSetNameToEncoding( (CFStringRef)ianaName ) ); NSString *someArgument = [NSString stringWithCString:argv[someIndex] encoding:encoding]; I find that a little crude, however -- which makes me think that I missed out something obvious...but what? Is there a saner/cleaner way of achieving essentially the same? Thanks in advance D

  • Can UMDF drivers be packaged/shipped via WiX?

    - by Rafael Rivera
    Howdy Internets: I put together a WiX 3.0 package, utilizing the DIFx extensions, with the intentions to install a Windows 7 Sensor (UMDF driver). During installation, DIFXAPP logged "No matching devices found in INF" and simply threw the driver into storage. I read I'm to populate my INF with an appropriate DriverPackageType, but according to MSDN's enumerated list, nothing fits. Is UMDF driver installation a supported scenario? If not, what's the best practice for using WiX to install such drivers? Disassembling the DIfx extension shows intent to support Co-installer packages, I have yet to try 3.5 beta.

  • Load Balancer recommendations

    - by delerious010
    I provide hosting service for about 250 clients to date, and this is increasing on a monthly basis. For each client, I have 2 "services" configured for L4 balancing / persistence .. one on port 80, another for port 443 which redirects to another internal port as well as 4 servers per service. This equates to a total of 500 "services" and 2000 "servers". I'm currently running with a couple CoyotePoint load balancers, and have had a look at some Barracudas but so far I'm really not impressed by those. Could anyone recommend some good load balancers which would be able to support this sort of load ? And which offer a good API, or shell access to automate management.

  • dmenu doesn't set environment variable as per my .bash_profile when running Emacs

    - by proofit404
    I have following ~/.bash_profile [[ -f ~/.bashrc ]] && . ~/.bashrc and ~/.bashrc ### Check for shell interactivity. if [[ $- != *i* ]] ; then return fi ### Nyan-cat prompt.

When I start it with dmenu (getenv "PATH") and exec-path variable doesn't contain ~/bin directory. When I do it in xfce with xfrun4 command with same bash configuration all seams to work too. What is the problem with dmenu?

  • How to create a VS2010 extension that uses Language Services

    - by Hades32
    Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?

  • Linux bash: when to use egrep instead of grep?

    - by Michael Mao
    Hi all : I am preparing for a Linux terminal assessment now, I tried to Google and found most resources are referring to the basic "grep" rather than the more powerful "egrep" -- well, that is at least what the professor said in lecture. I am always working with small samples so performance tuning is a thing too far away. So basically I'd like to know are there any areas where I must switch to egrep to do it in a better way? Is it safe to work with basic "grep" as for now? will there be potential risks? Sorry about my limited knowledge on Linux shell commands, the man page looks like a maze to me and honestly I haven't put much time in understanding all the features both command provide.

  • IAR Embedded Workbench - setting endian-ness of variable

    - by Seidleroni
    I'm using IAR Embedded Workbench for ARM (ARM7TDMI-S) and the majority of my work is done using little-endian format. However, I saw in the manual that I can do something like : __big_endian int i, j; to declare those two variables as big endian (while the rest of the app as little endian). This seems like a fantastic feature, but when I try to compile, I always get the errror: Error[Pa002]: the type attribute "__big_endian" is not allowed on this declaration. The big endian line above is copied directly from the manual, but it does not work. This is a great feature of the compiler and would make life a big easier. Any ideas how to get it working? I have my language conformance set to 'Allow IAR extensions' on the C/C++ Compiler options tab on the IDE options.

  • Current alternative to the old CHECKSUM program

    - by faulty
    I'm looking for an application that does md5/sha hash check on specific files/folders periodically and store an index file per folder for future verification. I remember such application exist in DOS days, to detect files infected by virus. The main purpose for this is to detect corrupted copy of backup, as I understand that consumer grade hardware are not 100% error free when doing backup or file transfer from device to device. The hash can also be used to generate a list of changed files for backup. Most of the software I can find is hash manually. EDIT: Windows based application, preferably a shell extension which I can right click on a folder and do a checksum/verify all files in that folder. Even better if that can integrate with a backup/sync program like BeyondCopy

  • Mutt and msmtp interoperability

    - by illusionoflife
    I am working on configuring /mutt/ to send mail via /msmtp/. Strangely, if I user /msmtp/ from shell, all okay, that means, that .msmtprc is correct. However, mail sent with mutt do not come. I have this line in .muttrc. set sendmail="msmtp" How can I debug this problem? EDIT: I found, that if I send just text, like msmtp 'my-email' <<< "Hello", it works. But if I send fully builded email-header, it do not. Is it gmail politics or what?

  • who has the best online prep MCSE study materials?

    - by phill
    I'm studying for my Microsoft Certified Systems Engineer (MCSE) on my own and was wondering who you could recommend for study materials? I did shell out a bunch of money for a local class and when it came to taking the test, there were a slew of topics which weren't even covered. For example, in my 070-293 test, they didn't even touch such as Certificates, how to setup clusters, sql server clustering, etcs. I realize there is a bunch out there such as cbtnuggets, preplogic, etcs. Which online preps do you suggest best preps you for the tests before I spend any more money on this stuff? thanks in advance

  • How can I get vim to set an ACL on its swap files?

    - by thsutton
    I use vim on an OS X Snow Leopard Server machine. A number of the directories I work in have ACLs (so that various groups of users can access them over AFP) that are inherited. For some reason, when I'm working in one of these directories, vim cannot read it's own swap files. It can create them fine but can't read them which, for some reason, makes it display the "swap file already exists" message (and no, the swap file does not already exist). vim -r lists the newly created swap file as "[cannot be read]". The owner and group are correct and the permissions are 0600, and the ACLs on the swap file and the file I'm editing are identical (as disclosed by ls -le and compared with diff). groups returns the same thing whether invoked from my login shell or via :! in vim. Has anyone encountered (and hopefully resolved) a problem like this before?

  • Urgent SSH Local Port Redirection

    - by Salina Odelva
    Hi, everyone. I have a shell account but the admin has restricted ssh access to the server. The server is listening on 0.0.0.0:22 but the firewall blocks any incoming attempts to this port. He says he is doing maintenance but I don't believe him and I need to backup my stuff with ssh. My question is that: Is it possible to do this: Me (Wan IP) <- Hosting Server (tcp/8080) redirects to Hosting Server (tcp/22) I don't want to involve my own linux machine in this and I can only make use of ssh.. Thanks!!

  • username and password for rsync in script

    - by sims
    I'm creating a cron job to keep two dirs in sync. I'm using rsync. I'm running an rsync daemon. I read the manual and it says: RSYNC_PASSWORD Setting RSYNC_PASSWORD to the required password allows you to run authenticated rsync connections to an rsync daemon without user intervention. Note that this does not supply a password to a shell transport such as ssh. USER or LOGNAME The USER or LOGNAME environment variables are used to determine the default username sent to an rsync daemon. If neither is set, the username defaults to 'nobody' I have something like: #!/bin/bash USER=name RSYNC_PASSWORD=pass DEST="server::module" /usr/bin/rsync -rltvvv . $DEST I also tried exporting (dangerous, I know) USER and RSYNC_PASSWORD. I also tried with LOGNAME. Nothing works. Am I doing this correctly?

  • Testing ASP.NET security in Firefox

    - by blahblah
    I'm not sure whether this question belongs on StackOverflow or SuperUser, but here goes nothing... I'm trying to test out some basic security problems on my personal ASP.NET website to see exactly how the custom validators, etc. work when tampering with the data. I've been looking at the Firefox extension TamperData which seems to do the trick, but it doesn't feel very professional at all. The issues I'm having with TamperData is that the textbox for the POST data is way too small to hold the ASP.NET view-state, so I have to copy that data into Emacs and then back again to be productive at all. I also don't like that there doesn't seem to be an option to only tamper with data which is from/to localhost. Any ideas on better extensions for the task or better methods to test it?

  • Log rotation with automatic *.log file discovery

    - by Mikko Ohtamaa
    I am hosting several websites which each of run their own Python process and write *.log output files, but the directory structure is not standardized. Example: -rw-r--r-- 1 plone plone 125M 2012-08-29 11:35 ./x/var/log/instance-Z2.log -rw-r--r-- 1 plone plone 19M 2012-08-29 00:07 ./zope2.9/y/log/event.log -rw-r--r-- 1 plone plone 188M 2012-08-13 00:09 ./zope2.9/y/log/Z2.log -rw-r--r-- 1 plone plone 137M 2010-11-16 09:41 ./zope2.9/y/log/event.log I'd like to make log rotate autodiscovery these log files and run a log rotation on them, as opposite to manually type in every log file to logrotate conf. Does any existing tools offer this kind of log file discovery and rotation capabilities, without manually specifying each file? If not... then just write a shell script which generates the logrotate conf?
