If you rebase and delete a lot of remote branches via git, your list of branches will end up showing branches on origin that no longer exist. This command will clear them out. Show Sample Output

This of course assumes that lesspipe is installed. You can view the contents of many, many types of files in this way. Once lesspipe is installed, add to your .bashrc export LESSOPEN="| /usr/bin/lesspipe %s" less file.jar export LESSCLOSE="/usr/bin/lesspipe %s %s" or eval "$(lesspipe)"
0LESSOPEN="| /usr/bin/lesspipe %s" less file.jar -
Output made so that it will match initial suggestion for this task. Personally, I think that output of du -h is more readable.
0find . -type f -size +20000k -print0 | xargs -0 du -h | awk -F"\t" '{printf "%s : %s\n", $2, $1}' -
0ps -u `/usr/xpg4/bin/id -u`

Avoids the nested 'find' commands but doesn't seem to run any faster than syssyphus's solution.
0find . -type f -size +0 -printf "%-25s%p\n" | sort -n | uniq -D -w 25 | sed 's/^\w* *\(.*\)/md5sum "\1"/' | sh | sort | uniq -w32 --all-repeated=separate -
Updated to the new version of the MW webpage (seems MW does not use cougar anymore, so the other commands do not work nowadays), and using Xidel to parse the page with a html parser instead regex. Example usage:
pronounce onomatopoeticI'm not sure how well Xidel works with binary streams (although it seems to work great in tests), so using wget to download the actual wav file might be safer, i.e.:pronounce(){ wget -qO- $(xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -e 'css("embed")[1]/@src') | aplay -q;}Xidel is not a standard cli tool and has to be downloaded from xidel.sourceforge.net0pronounce(){ xidel "http://www.m-w.com/dictionary/$*" -f "replace(css('.au')[1]/@onclick,\".*'([^']+)', *'([^']+)'.*\", '/audio.php?file=\$1&word=\$2')" -f 'css("embed")[1]/@src' --download - | aplay -q;} -
clush (cluster sh) is a very powerful tool to perform this kind of tests. The [a-b] syntax is expanded by clush. You can also play with names: cn[001-010] expands to cn001, cn002, cn003 .. cn010. Note that does not expands to cn1, cn2, etc., which is very useful, cause normally servers are named cn001, cn002... cn100
0clush -w 192.168.100.[1-50] -t 10 'uptime' -
0for i in $(find . -regex '.*\/C.*\.cpp'); do svn mv `perl -e 'my $s=$ARGV[0]; $s=~m/(.*\/)C(.*)/; print "$s $1$2"' "$i"`; done
-
You can create a backup of a directory which does not contain disturbing .svn and similar directories with that command.
0tar -cvj --exclude-vcs -f archive.tar.bz2 somedirectory -
perl version of "Wait for file to stop changing" When "FileName" has not been changed for last 10 seconds, then print "DONE" "10" in "(stat)[10]" means ctime. One have other options like atime, mtime and others. http://perldoc.perl.org/functions/stat.html
0echo FileName | perl -nlE'sleep 1 while time-(stat)[10]<10' && echo DONE -
0sudo sh -c "rm /usr/share/mime/packages/kde.xml && update-mime-database /usr/share/mime"
-
0emacs -f snake
-
to kill, use `kill PID` Credit: user Craig Ringer on stackexchange.com, recommends to kill the process rather than deleting postmaster.pid when there is an orphan Postgresql server process. Show Sample Output
0cat /usr/local/var/postgres/postmaster.pid -
Might not work if your devices is older than Lollipop (5.0). Verified on macOS, and most likely work on Linux as well.
0adb exec-out screencap -p > screenshot.png -
0find . -name Root -print | xargs rm -f
-
That one works on Linux. On BSD and Solaris, the ifconfig output is much easier to parse:
/sbin/ifconfig -a | awk '/inet/{print $2}'0/sbin/ifconfig | awk -F'[ :]+' '/inet addr/{print $4}' -
Same thing, only "head" instead of grep/egrep.. Show Sample Output
0find -type f |while read a;do [ "`head -c3 -- "${a}"`" == $'\xef\xbb\xbf' ] && echo "Match: ${a}";done -
// This is description for the old command: Unfortunately we to encode the URL. It can't be done with bash (without building it ourselves) so I used Perl? Example with Perl:
curl -s http://is.gd/api.php?longurl=`perl -MURI::Escape -e "print uri_escape('http://www.google.com/search?hl=en&source=hp&q=commandlinefu&aq=0&oq=commandline');"`Example without Perl:curl http://is.gd/api.php?longurl=http://www.google.comMost urls doesn't use & and ? anymore (SEO etc) so in most cases you can just use the simple version. :) Show Sample Output0curl -s "http://is.gd/api.php?longurl=[long_url]" -
Changed out the for loop for an xargs. It's a tad shorter, and a tad cleaner.
0find . -type f |xargs -I% sed -i '/group name/s/>/ deleteMissing="true">/' % -
Prints movie length in H:MM:SS format with appropriate leading zeros. Show Sample Output
0mplayer -vo null -ao null -frames 0 -identify movie.avi | awk '{FS="="}; /ID_LENGTH/{ H=int($2/3600); M=int(($2-H*3600)/60); S=int($2%60); printf "%d:%02d:%02d\n",H,M,S}' - ‹ First < 390 391 392 393 394 > Last ›
