  • Inserts the results of an autocompletion in the command line

    Pressing ESC then * will insert in the command line the results of the autocompletion. It's hard to explain but if you look the sample output or do echo ESC * you will understand quickly. By the way, few reminders about ESC : - Hold ESC does the same thing as tab tab - 'ESC .' inserts the last argument of last command (can be done many times in order to get the last argument of all previous commands) Show Sample Output

  • ignore the .svn directory in filename completion

    When browsing java source code (for example) it's really annoying having to type the first letter of the package when there is only one package in the subdir. man bash for more info about FIGNORE

    export FIGNORE=.svn

  • Define an alias with a correct completion

    In Bash, when defining an alias, one usually loses the completion related to the function used in that alias (that completion is usually defined in /etc/bash_completion using the complete builtin). It's easy to reuse the work done for that completion in order to have smart completion for our alias. That's what is done by this command line (that's only an example but it may be very easy to reuse). Note 1 : You can use given command line in a loop "for old in apt-get apt-cache" if you want to define aliases like that for many commands. Note 2 : You can put the output of the command directly in your .bashrc file (after the ". /etc/bash_completion") to always have the alias and its completion Show Sample Output

    old='apt-get'; new="su-${old}"; command="sudo ${old}"; alias "${new}=${command}"; $( complete | sed -n "s/${old}$/${new}/p" ); alias ${new}; complete -p ${new}

  • enable all bash completions in gentoo

    enable each bash completion that you have installed at your system, that's very nice ;)

  • expand a program-name into an absolute path on the bash command-line, using ctrl-e

    Tested with bash v4.1.5 on ubuntu 10.10 Limitations: as written above, only works for programs with no file extention (i.e 'proggy', but not 'proggy.sh') because \eb maps to readine function backward-word rather then shell-backward-word (which is unbinded by default on ubuntu), and correspondingly for \ef. if you're willing to have Ctrl-f and Ctrl-g taken up too , you can insert the following lines into ~/.inputrc, in which case invoking Ctrl-e will do the right thing both for "proggy" and "proggy.sh". -- cut here -- \C-f:shell-backward-word \C-g:shell-forward-word "\C-e":"\C-f`which \C-g`\e\C-e" -- cut here -- Show Sample Output

    bind '"\C-e":"\eb `which \ef`\e\C-e"'

  • Autocomplete directories (CWDs) of other ZSH processes

    It gives a 'xcd' command for changing directory to one of CWDs of other ZSH processes (typically running in a terminal emulator). Useful for single-windowed terminal emulators like XTerm or Rxvt which don't have ability to pass CWD of one shell to another. Show Sample Output

    function _xterm_cwds() { for pid in $(pidof -- -zsh) $(pidof zsh); do reply+=$(readlink /proc/$pid/cwd) done }; function xcd() { cd $1 }; compctl -K _xterm_cwds xcd

  • enable all bash completions in gentoo

    Pros: * it's much faster then for loop * removes first line of 'eselect bashcomp list' - which contains text "Available completions:"

  • Autocomplete directories (CWDs) of other ZSH processes (MacOS version)

    MacOS Solution due to lack of pidof command and procfs on MacOS Kernel. Show Sample Output

  • Ultra shortcut for ssh root@

    When you have to manage lot of servers, it's boring to type ssh root@myhost for each connection. Now you can type juste "s someting" and you are connected. You can too add bash_completion script to complet with tab the name of your servers. This will be the next tips from me ;) Show Sample Output


    -20
    alias s='ssh -l root'

Keep track of diff progress
When running a long `diff -r` over folders, this simulates a "verbose" mode where you can see where diff is in the tree. Replace $file with the first part of the path being compared.

Find out when your billion-second anniversary is (was).
This is the same command as this one, but for OS X. http://www.commandlinefu.com/commands/view/3053/find-out-when-your-billion-second-anniversary-is-was.

Press ctrl+r in a bash shell and type a few letters of a previous command
In the sample output, I pressed ctrl+r and typed the letters las. I can't imagine how much typing this has saved me.

Read null character seperated fields from a file
Handle any bad named file which contains ",',\n,\b,\t,` etc Store the file name as null character separated list $find . -print0 >name.lst and retrieve it using $read -r -d "" Eg: $find . -print0 >name.lst; $cat name.lst| while IFS="" read -r -d "" file; $do $ls -l "$file"; $done

Check if a remote port is up using dnstools.com (i.e. from behind a firewall/proxy)

Quick searching with less
This command enables the user to append a search pattern on the command line when using less as the PAGER. This is especially convenient (as the example shows) in compressed files and when searching man pages (substituting the zcat command with man, however).
