  • Grabs the cmdline used to execute the process, and the environment that the process is being run under. This is much different than the 'env' command, which only lists the environment for the shell. This is very useful (to me at least) to debug various processes on my server. For example, this lets me see the environment that my apache, mysqld, bind, and other server processes have. Here's a function I use: aa_ps_all () { ( cd /proc && command ps -A -opid= | xargs -I'{}' sh -c 'test $PPID -ne {}&&test -r {}/cmdline&&echo -e "\n[{}]"&&tr -s "\000" " "<{}/cmdline&&echo&&tr -s "\000\033" "\nE"<{}/environ|sort&&cat {}/limits' ); } From my .bash_profile at http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Show Sample Output

  • Run program as root by SSH key forwarding instead of sudoers. Put this alias line in .bashrc or wherever you like. Alias arguments might need extra escaping. You might wonder about security. But you'd block out root login as much as possible of course. In sshd_config you put this: PermitRootLogin no Match Address 127.0.0.1   PermitRootLogin without-password


    -2
    alias sshdo='ssh -q -t root@localhost -- cd $PWD \&\& sudo'

  • Set a bookmark as normal shell variable p=/cumbersome/path/to/project To go there to p This saves one "$" and is faster to type ;-) The variable is still useful as such: vim $p/<TAB> will expand the variable (at least in bash) and show a list of files to edit. If setting the bookmarks is too much typing you could add another function bm() { eval $1=$(pwd); } then bookmark the current directory with bm p

  • This function does a batch edition of all OOO3 Writer files in current directory. It uses sed to search a FOO pattern into body text of each file, then replace it to foo pattern (only the first match) . I did it because I've some hundreds of OOO3 Writer files where I did need to edit one word in each ones and open up each file in OOO3 gui wasn't an option. Usage: bsro3 FOO foo

  • This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead. I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'. Show Sample Output

  • Each shell function has its own summary line, as a comment. If there are multiple shell functions with the same name, the function with the highest number of votes is put into the file. Note: added 'grep -v' to the end of the pipeline, to eliminate extraneous lines containing only '--'. Thanks to matthewbauer for pointing this out.
