Commands tagged completion (11)

  • 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

  • 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

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

  • 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

  • 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

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

  • 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

    alias s='ssh -l root'

Monitor ElasticSearch cluster health - Useful for keeping an eye on ES when rebalancing takes place

Takes and displays screenshot of Android phone over adb.
Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

Check if *hardware* is 32bit or 64bit
This command tell you if your hardware is 32 or 64 bits even if you install a 32bits OS on a 64 bits hardware. If your distro don't support the -q switch, try doing : $ grep &>/dev/null '\' /proc/cpuinfo && echo 64 bits || echo 32 bits

urldecoding with one pure BASH builtin
You can use ordinary printf to convert "%23%21%2fbin%2fbash" into "#!/bin/bash" with no external utilities, by using a little known printf feature -- the "%b" specifier converts shell escapes. Replace % with \x and printf will understand the urlencoded string. BASH's printf has an extension to set a variable directly, too. So you get to convert urlencoded strings from garble to plaintext in one step with no externals and no backticks.

Steve Reich - Piano Phase; interpreter: Bourne-Again Shell.
The Piano Phase piece, by Steve Reich is a minimalist composition which is played on two pianos played at slightly different tempos, a task that's very difficult to accomplish by human players. The auditive effects produced by the cell displacement produce beautiful patterns. See https://en.wikipedia.org/wiki/Piano_Phase . My rendered version: https://ydor.org/SteveReich/piano_phase.mp3 Requires sox to be installed on the system. There are multiple videos on youtube showing different approaches and experiences to this interpretation. There is also a synthesized version. Even if Bash can behave as a powerful pianist, a simple threaded version leaves full room to several time glitches and even negative displacements, the same issues that human pianists experience when playing the piece. The older the computer, the better the chaos added to the result due to the CPU load. Apparently that's the reason Steve Reich composes pieces such as this. Without further ado, please give a warm welcome to the Bash minimalist player on synthesized two-threaded pianos. Please turn off your cellphones.

Show the total number of changes that every user committed to a Subversion repository
This saves Subversion's log output as XML and then runs an XQuery over it. This is standard XQuery 1.0 and should therefore also work with other XQuery processors. I have tested it with Zorba (http://www.zorba-xquery.com). XQilla (http://xqilla.sourceforge.net) also does it, but you'd have to save the query to a file and then execute "xqilla filename.xq". The query first finds all distinct authors and then, for each author, sums up the number of paths they have changed in each commit. This accounts for commits of multiple changes at once. The indenting space in all lines from the second one seems to be due to a bug in Zorba.

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }
