Ubuntu :: Shell - Command-dependent <tab> Autocomplete?

Jul 6, 2010

I was using windows recently and noticed that in their command line, the autocomplete is in some ways a little more intelligent (although based on my short experience ours is more robust); for example, if you have a directory named blah and a file name bl, in Linux "cd bl <tab>" will result in "cd bl" while in Windows I get "cd blah" because it recognizes that blah and not bl is the appropriate argument to cd. Similarly unrar will target rar files first.I am not saying Windows command line is better; Windows command line is in general a piece of junk.

Ubuntu :: Test Command In Shell Script?

Aug 29, 2010

I was trying to write a script, but for some reason I can't test two variables using -gt:

a=`expr $currentSize + 0`
b=`expr $fileSize + 0`
[$a -gt $b]
this is what I get:
[22234534: not found

what is the problem? It seems like I can't check if a variable is greater than another but only if a variable is greater than a fixed number. Is that so? By the way the variables $fileSize and $currentSize exist and $a and $b have a value.

Ubuntu Servers :: Run A Shell Command As Another User?

Apr 26, 2011

The short version: I have to manage some virtual machines using php shell_exec function, so far I cant do this because apache is run by the user www-data and virtualbox by the user vboxuserFrom what I've read so far, I've thought of 3 possible solutions: 1.- Create a script on my vboxuser that I can call from php to manage the Virtual Machines.2.- Change the apache user from www-data to vboxuser so I can manage the Virtual Machines through php
3.- Reinstall VirtualBox, this time using www-data as my user. I'm not sure if any of these will work and I'm not too sure of which would be the best solutionNow the longer more detailed version:

I have a remote server running Ubuntu 10.04.2, in that server I have set up VirtualBox so I can run several instances of WinXP to perform different tasks. Everything is setup and I can manage the virtual machines through SSH. If I want to run them as a different user than the one that created them (a user that so far only has been used to create the Virtual Machines) I have to do sudo -u vboxuser.Now, I need to create a PHP script to manage these virtual machines (I know about phpVirtualBox, but it's not what I need). If I try to run the virtual machines using shell_exec() from php, I get no answer at all (And I have tested that shell_exec is working on my server).

Ubuntu :: Emacs -- Run Shell Command W/o Output?

Jul 12, 2011

I write LaTeX in Emacs and then run a shell script to process the LaTeX code. I used to run a subshell buffer with M-x shell and then execute the script from within there, but this results in a lot of switching between buffers, which seems unnecessary. Then, I found out about executing shell commands with M-! cmd RET, as described here:[URL]The problem with this is that the output from the script splits my screen. It's a nuisance, and I would like to run the script without any output. I've tried appending > /dev/null to the command, but it doesn't work.For example, when from within Emacs I enter M-! followed by

sh make.sh > /dev/null
it splits my screen so that one portion displays output from the make.sh script. I want it to run silently, and leave my Emacs buffers alone

Ubuntu :: Shell Command Output Not Showing Immediately?

Jan 18, 2011

This is an extremely weird issue that I can't find any help with on Google. It is minor but extremely annoying.

When I type in a linux command in the terminal, (e.g. "ls -la"), and then press enter, the cursor goes to the next line and just sits there, as if its processing some long command.

If I press enter again, I see the ls output as well as my prompt twice. It's like the terminal window isn't auto-scrolling, but I've also seen this happen when there wasnt even enough text in the console screen to warrant a scrollbar. Has anyone seen this before and know what I need to do? I hope what I'm asking about makes sense.

Ubuntu :: Bash Shell Implements Version Of The Command?

Mar 19, 2011

I'm used to being able to put a script in ~/bin and having it overrule the system version of a command. However for "time" or "kill" since the bash shell implements a version of the command (i.e. /bin/ version is not used) doing this is not enough. How can I get the shell to run my own version instead of the version in the shell.I understand the implications of doing this. I know what I'm doing, I can always /bin/whatever if I want to get the old version (or just chmod -x ~/bin/whatever).

Server :: Which Php Command For Shell Interaction Shall Use?

Dec 26, 2010

As homework for my study I have to do some kind of browser GUI to send commands to mysql command line tool and to show the output in the browser. I already set up sudo to have the right permissions for the www-data user. In the php documentation I found that one of the following four commands are probably for tasks like mine.

shell exec

Can anyone tell me which one is the best for my requirements? The idea is to use php from the browser to connect to mysql like on the command line with: "mysql �user=username �password" And then give back the output of the command line to the browser. If the above is working then the next step would be to put a link in order to execute the command �show database;� again through php by clicking that link. After clicking this link it would give back to the browser what the command line would display.

Programming :: Executing Shell Command In JSP

Aug 24, 2010

what we are trying to do is, to let the customer click a button in the web browser, and then the web server to call a shell script to do the work. The output from the stdout && stderr of the script should be displayed in the web browser once finished or timeout, along with the exit code of the script.

The shell script is however not on the web server, but on another app server. So to call this script from the web server as the identity 'tomcat':

$ sh appuser@app-server:$appbin/app-script

The .ssh/id_rsa.pub thing is done, and we have no problem doing this in the command line so far.

Our loaded ex-colleage has left us the webpages (jsp) with code like these:

<%@ include file="jsp_functions.jsp" %>
String cmd = "sh $appbin/app-script";
ExecResult r = new ExecResult();

Ubuntu :: 'set' Command In Terminal Has Shell Scripts Embedded Inside?

May 3, 2010

I just installed Ubuntu 10.04 for some development. I was trying to set some environment variables are noticed that when I hit 'set' inside a terminal (to dump environment vars) I get the usual first few variables but then I see a whole lot of script code ....




I've installed a lot of tools (NetBeans, Ruby, Java, build-essentials etc) but essentially I installed Ubuntu today - so it shouldn't have rotted out this quickly. is this hijacking of environment vars to embed script code intentional with Ubuntu 10.04?

General :: Backslash Preceding A Shell Command

Mar 21, 2011

Reading a BASH script, I saw a find command preceded with a backslash. It was similar to this:

`find . -type f -name '*.xml' -print > xmlfilelist`

It's impossible to find documentation about this in man pages or on the internet, since 'backslash' are always evoked along with special characters. I also noticed that even though the command was surrounded with backquotes, the result was not affected to any variable. Maybe the backslash's presence is related with this?
