  • Most effective way to change Linux command prompt for all users?

    - by incredimike
    I have several machines and the hostnames are really long.. i.e. companyname-ux-staging-web1.companyname.com. So my prompt looks something like [root@mycompany-ux-staging-web1 ~]# I'd like to shorten that up for all users on all machines with the least amount of work. From what I read I have a couple options, but they all have their drawbacks. I could change the hostname, but that would likely affect applications. Not a great choice. I could alter also $PS1 at login for all users by editing all .bashrc for existing users, and edit /etc/skel/.bashrc for potential new users. That's a lot of work across 10 machines. What's my best option or what have I overlooked?

  • set a global environment variable in linux that sticks when going root

    - by Scott
    When I SSH into a linux box, I want to have the /etc/profile file save the results of the whoami command to a global environment variable. if I were to go root with the command sudo su -, I do not want that command to run again when gonig root, I want it to stick with the result of whoami as my regular username from before I went root, and I need to access that variable as the root user even though it will run the /etc/profile file again when I go root. What can I do to only run that command once in the /etc/profile command?

  • Automate hashing for each file in a folder?

    - by Kennie R.
    I have quite a few FTP folders, and I add a few each month and prefer to leave some sort of method of verifying their integrity, for example the files MD5SUMS, SHA256SUMS, ... which I could create using a script. Take for example: find ./ -type f -exec md5sum $1 {} \; This works fine, but when I run it each time for each shaxxx sum afterwards, it creates a sum of the MD5SUMs file which is really not wanted. Is there a simpler way, or script, or common way of hashing all the files in to their sums file without causing problems like that? I could really use a better option.

  • Find directories that do not contain a directory?

    - by erikcw
    I'm trying to figure out how to use the linux "find" command (or another command that will get the job done) to return a list of file paths/directories that do not contain a directory of a certain name. ~/web/domain1.com/public_html/bar ~/web/domain2.com/public_html/ ~/web/domain3.com/public_html/bar ~/web/domain4.com/public_html/ I want all of the paths that don't contain the directory named "bar" (domain2.com and domain4.com). Any idea how I can get find to output such a list? Thanks!

  • Run shell script on Linux box from a shortcut/app in Android?

    - by melat0nin
    I have an Ubuntu box which runs XBMC, which crashes occasionally. Since I have no keyboard connected,I have to SSH in, kill xinit, then restart it. I was wondering if there's an elegant way of doing this from my Android tablet, so I don't have to go to my desktop PC. I've used ConnectBot and can log in, but typing is laborious, even using the edit keys to scroll back up through the buffer. It seems as though it should be possible to script this so that I can execute a shortcut, or at least select a predefined script to be executed. This would seem to have plenty of applications, and there could be a site of scripts - restart webserver, reboot, email logs etc

  • Run script on login with ssh

    - by user912447
    I have a feeling this is quite easy to do but every solution found on google has to do with adding a script to be run whenever someone logs into the machine. What I am looking for is a way to run a script when only I log into the machine. I ssh into a shared computer and need to have it load a couple modules for me and I imagined the easiest way to do this would to just run a script on login. Is there a simple way?

  • Kill all currently running cron jobs

    - by Adelphia
    For some reason my cron job scripts aren't exiting cleanly and they're backing up my server. There are currently a couple hundred processes running for one of my users. I can use the following command to kill all processes by that user, but how can I simplify this to kill only crons? pgrep -U username | while read id ; do kill -6 $id ; done It would be dangerous to run the above command as is, correct? Wouldn't that kill mysql and other important things?

  • Is there a "pattern" or a group that defines *rc files in *nix environments?

    - by Somebody still uses you MS-DOS
    I'm starting to use command line a little more, and I see there are a lot of ways to configure some config files in my $HOME. This is good, since you can customize it the way you really like. Unfortunately, for begginners, having too many options is a little confusing. For example, I created .bash_alias for some alias I'm using. I didn't even know this option existed, I'm used to simply edit .bashrc. Do exist a pattern, a "good practice", envisioning flexibility and modularity in terms of rc files structure? Do exist a standardization group for this, or every body just creates it's own configuration setup?

  • Parallel shell loops

    - by brubelsabs
    Hi, I want to process many files and since I've here a bunch of cores I want to do it in parallel: for i in *.myfiles; do do_something $i `derived_params $i` other_params; done I know of a Makefile solution but my commands needs the arguments out of the shell globbing list. What I found is: > function pwait() { > while [ $(jobs -p | wc -l) -ge $1 ]; do > sleep 1 > done > } > To use it, all one has to do is put & after the jobs and a pwait call, the parameter gives the number of parallel processes: > for i in *; do > do_something $i & > pwait 10 > done But this doesn't work very well, e.g. I tried it with e.g. a for loop converting many files but giving me error and left jobs undone. I can't belive that this isn't done yet since the discussion on zsh mailing list is so old by now. So do you know any better?

  • What is a good way to get back to the command prompt discarding STDOUT and STDERR

    - by elementz
    I often launch applications from the cli via e.g. command & to immediately get back to the prompt back. The downside of this is, that I still get STDOUT and STDERR. So I use command &> /dev/null to discard those outputs. This can get quite a chore, when having to write this often during a day. So my question is, is there a better (read shorter) way to discard of STDOUT and STDERR when not needed? What could be done? write a wrapper script to launch applications? What would be an elegant way to do this?

  • How to check there are no html files in current directory?

    - by kev
    I have a script which will download html files into current directory. Then it'll generate a report based on these html files. At last, it'll delete all these html files. So, when I run this script, I want to make sure there is no html files in current dir. This is what I got: if ls *.html >/dev/null 2>&1; then echo 'clear HTML files first' exit fi Is there any easy way to check?

  • Where is OS X's $PATH set?

    - by thepurplepixel
    I have a little $PATH problem: I just reinstalled MacPorts, and my path contains the MacPorts directories as it should at the beginning of $PATH. However, despite me having no such setting in my ~/.bashrc, ~/.bash_profile or ~/.profile, /Library/Frameworks/Python.framework/Versions/2.6/bin is somehow getting appended to the beginning of my $PATH: 0 07:15:11pm ~ $ echo $PATH /Library/Frameworks/Python.framework/Versions/2.6/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin I'd like to remove it as the MacPorts version of Python is newer. This must be appended after all the above-listed files are read, but I can't think of where. There is no mention of this in /etc/profile, /etc/bashrc or /etc/paths. Any assistance would be greatly appreciated. Thanks!

  • tab completion for service command on debian

    - by markus
    I have two systems with debian squeeze installed. On one system when I type: service <TAB> it shows me all available service (from /etc/init.d) on the other system it shows me all files from the current directory. Does anyone know which setting changes that behaviour ? UPDATE: The file /etc/bash_completion.d/service was missing. I copied it from the machine where it is working. If I type complete -p | grep service it shows me: complete -F _service service On the machine where it is not working that command shows me nothing. I executed complete -F _service service in the command line, after that, the command service <TAB> shows me: service -su: completion: function `_service' not found this function is defined in the service file I recently copied, for some reasons it can't be found ...

  • How to run script from root as another user (with user PATH)

    - by Sandra
    I would like to have these commands run as the ss user from root mkdir bin cp -r /opt/gitolite . gitolite/install -ln gitolite setup -pk ss.pub mkdir -p .gitolite/hooks/common ln -s /opt/pre-receive .gitolite/hooks/common/ so everything is executed in /home/ss. The 4th line requires $HOME/bin as you can see from the 3rd line. The only way I can get it to work is by adding su -c "command" ss to each line, which is not a nice hack. This is an extension to my previous question, where I wasn't precise enough. Question How do I run all these commands as a script in a practical way?

  • what TERM to use to get rid of color escape codes?

    - by slivu
    Is there a way to get rid of escape codes in terminal output? Say even if the script are sending that codes they are ignored by terminal and text displayed as is, without colors, bolds etc. I need to display terminal output on a HTML page. For now i'm using javascript to remove escape codes, but it becomes clunky cause i receive output by chars, and have to wait until all content received then update it, leading in weird effects.

  • Is \d equal to [0-9] in sed?

    - by user3872279

I wanna the lines which doesn't start with number. In practice, sed -i '/^[0-9]+/d' 2.txt works good. However, sed -i '/^\d+/d' 2.txt doesnot. The \d shouldn't be equal to [0-9] in regex?

  • how to start growl via the command line

    - by adam n
    I have a bash script that uses growlnotify to send notifications. However, growlnotify doesn't work if Growl isn't already running, and it won't auto start Growl if it needs it, either. So I want to be able to check if Growl is running, and then start it if it isn't. I'm thinking of doing something like: g=$(ps -e | grep Growl | grep -v grep) if [ -z "$g" ] # Growl isn't running then # (start Growl) fi How would I start Growl via the command line?
