Thanks to the great grml team for this func! You really should look at their shell configs for further usefull things! http://git.grml.org/?p=grml-etc-core.git;a=blob_plain;f=etc/grml/script-functions;h=4d6bcea8f9beae83abd08f44155d299ea54a4a9f;hb=HEAD # {{{ check for availability of program(s) # usage example: # check4progs [-s,-q,--quiet,--silent] arg [arg .... argn] # # with option given either of: # -s,-q,--quiet,--silent # # check for available progs but produce no output check4progs() { [ -n "${ZSH_VERSION}" ] && emulate -L sh local RTN=0 local oldifs="${IFS}" local ARG d found local VERBOSE=1 case ${1} in -q | -s | --quiet | --silent) VERBOSE=0 shift 1 ;; *) ;; esac while [ $# -gt 0 ] do ARG="$1" shift found=0 IFS=: for d in $PATH do if [ -x "${d}/${ARG}" ] then found=1 break fi done IFS="${oldifs}" # check for availability if [ ${found} -eq 0 ] then if [ ${VERBOSE} -eq 1 ] then printf "%s: binary not found\n" "${ARG}" >&2 fi RTN=1 fi done # return non zero, if at least one prog is missing! return $RTN } # }}} Show Sample Output

some people on the net already use a cd(), but most of them break 'cd -' functionality, that is "go back where you have been previosly", or 'cd' which is "go back home". This cd() copes with that. Also when given a file name, go to the directory where this file is in. cd() { if [[ -n ${*} ]] then if [[ s${*}e == s-e ]] then builtin cd - elif [[ ! -d ${*} ]] then builtin cd "${*%/*}" else builtin cd "${*}" fi else builtin cd ~ fi ls -la }

Type out the command and simply press to see the list of options for that command without having to type --help. Show Sample Output

Allow to launch nc like a daemon, in background until you still stop it. (like this command: http://www.commandlinefu.com/commands/view/9978 ) For send script or commands from the client to the server, use nc too, like that : cat script.sh | nc server 1025 echo "service openvpn restart" | nc server 1025 The loop's inside doesn't do anything, but we can add echo -e "\nCommand received\n" .

write first line `#!`

This allows you to search through your history using the up and down arrows ? i.e. type "cd /" and press the up arrow and you'll search through everything in your history that starts with "cd /". Show Sample Output

Takes filenames and directory names and replace space to '_'.

This opens up nautilus in the current directory, which is useful for some quick file management that isn't efficiently done from a terminal.

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know Show Sample Output

# put this in your .bashrc mkgo (){ mkdir $1 && cd $1 } Show Sample Output

Sometimes you want to know the summary of the sizes of directories without seeing the details in their subdirectories. Especially if it is going to just scroll off the screen. This one liner summarizes the disk usage of any number of directories in a directory without giving all the details of whats happening underneath. Show Sample Output

( IFS=:; for i in $PATH; do echo $i; done; ) echo $PATH|sed -e 's/:/\n/g' # but the tr one is even better of course echo $PATH|xargs -d: -i echo {} # but this comes up with an extra blank line; can't figure out why and don't have the time :( echo $PATH|cut -d: --output-delimiter=' ' -f1-99 # note -- you have to hit ENTER after the first QUOTE, then type the second one. Sneaky, huh? echo $PATH | perl -l -0x3a -pe 1 # same darn extra new line; again no time to investigate echo $PATH|perl -pe 's/:/\n/g' # too obvious; clearly I'm running out of ideas :-)
