Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

This is how I list the crontab for all the users on a given system that actually have a crontab.

You could wrap it with a function block and place it in your .profile or .bashrc for quick access.

There's prolly a simpler way to do this. Discuss.

sed -i '19375 s/^/#/' file

This will comment out a line, specified by line number, in a given file.

awk '{print length, $0;}' | sort -nr
find . -iname ".project"| xargs -I {} dirname {} | LC_ALL=C xargs -I {} svn info {} | grep "Last Changed Rev\|Path" | sed "s/Last Changed Rev: /;/" | sed "s/Path: //" | sed '$!N;s/\n//'

Functions: dirname find grep info sed xargs

Searches for all .project files in current folder and below and uses "svn info" to get the last changed revision. The last sed joins every two lines.

Refresh the cache of font directory , usefull after you download font (.ttf or other) from various website and you don't want to reboot or relogin . Close your word processor before using the command , after the refresh reopen your word processor , new fonts is avaible !

The really awesome bash completion in debian seems to be an extra package now, which has to be installed. After sourcing /etc/bash_completion it completes almost everything (package names in apt... etc) :-)

To make this permanent, put something like this in your .bashrc:

if [ -f /etc/bash_completion]; then

source /etc/bash_completion

fi

The "-d" option for gnu's "date" command can calculate positive or negative offset from any time, including "now". You can even specify a source timezone (the output timezone can be set with the TZ environment variable). Useful! Fun! Not very well documented!

Comments can be used directly on the command line so I can save in the history a brief description of what command does.

awk '{print(substr($0,1,5))}' file

Consider this file :

laminate

this

file

with awk

hello to

commandlinefu

I can use awk substring to laminate words :

lamin

this

file

with

hello

comma

find . -type f -exec sha1sum {} >> SHA1SUMS \;

All output is placed in file SHA1SUMS which you can later check with 'sha1sum --check'. Works on most Linux distros where 'sha1sum' is installed.

Nicely display in html format a detailed report of the machine, including cpu benchmarks.

Found another way, more compatible. Tested with xterm, aterm, gnome-terminal and rxvt (where it sets the window title) and guake (where it doesn't - after all, guake does not show the window title).

if [ "$SHELL" = '/bin/zsh' ]; then case $TERM in rxvt|*term|linux) preexec () { print -Pn "\e]0;$1\a" };; esac; fi

Force an fsck on reboot. Useful on a system where / has mounted read-only because of file system issues.

Works only on Linux.

Last option (n) turn name of service resolving (/etc/services) off.
