These days, most software distributed in tar files will just contain a directory at the top level, but some tar files don't have this and can leave you with a mess of files in the current folder if you blindly execute

tar zxvf something.tar.gz

This command can help you clean up after such a mistake. However, note that this has the potential to do bad things if someone has been *really* nasty with filenames.

ps -ef | grep $USERNAME | awk {'print $2'} | xargs kill [-9]

This is a 'killall' command equivalent where it is not available.

Prior to executing it, set the environment variable USERNAME to the username, whose processes you want to kill or replace the username with the $USERNAME on the command above.

Side effect: If any processes from other users, are running with a parameter of $USERNAME, they will be killed as well (assuming you are running this as root user)

[-9] in square brackets at the end of the command is optional and strongly suggested to be your last resort. I do not like to use it as the killed process leaves a lot of mess behind.

tar options may change ;)

c to compress into a tar file, z for gzip (j for bzip) man tar

-print0 and -0t are usefull for names with spaces, \, etc.

this will find text in the directory you specify and give you line where it appears.

For quick validation of folder's file-contents (structure not taken into account) - I use it mostly to check if two folders' contents are the same.

This command is useful when you want to know what process is responsible for a certain GUI application and what command you need to issue to launch it in terminal.

find . -type f -exec grep -l XXX {} \;|tee /tmp/fileschanged|xargs perl -pi.bak -e 's/XXX/YYY/g'

User: drossman
Functions: find grep perl tee xargs

Find all files that contain string XXX in them, change the string from XXX to YYY, make a backup copy of the file and save a list of files changed in /tmp/fileschanged.

find "$DIR" -regex "$FILENAME" -type f -print0 | xargs -0 sed -i _`date "+%y%m%d%H%M%S"` -E "s/$TEXT1/$TEXT2/g"

Functions: cut grep sed xargs

checking files in current and sub directories, finding out the files containing "sampleString" and removing the containing lines from the file.

* Beware that The command will update the original file [no backup].

The command can be extended if play with 'find' command together,

e.g. it is possible to execute on certain type of files: *.xml, *.txt... (find -name "*.xml" | grep....)

if anybody knows a better solution on that, please drop a comment. thx.

Create a tgz archive of all the files containing local changes relative to a subversion repository.

Add the '-q' option to only include files under version control:

svn st -q | cut -c 8- | sed 's/^/\"/;s/$/\"/' | xargs tar -czvf ../backup.tgz

Useful if you are not able to commit yet but want to create a quick backup of your work. Of course if you find yourself needing this it's probably a sign you should be using a branch, patches or distributed version control (git, mercurial, etc..)
