Commands using xargs

This command removes *.lock or files from a folder.

This is great when you need to reboot the system-server, or your own daemon that has gone crazy

This let me find some a set of modifications that were made to a rather large tree of files, where the file-names themselves were not unique (actually: insanely redundant and useless. "1.dat 2.dat ..."). Pruning down to last-branch brough things back to the "project-name" scope, and it's then easy to see which branches of the tree have recently changed, or any other similar search.

Ideally, it should sort the directories by the mtime of the most recent *file* *inside* the directory, but that's probably outside the scope of a (sane...) command line.

useful to count events in logs

When working with jailed environments you need to copy all the shared libraries to your jail environment. This is done by running ldd on a binary which needs to run inside the jail. This command will use the output from ldd to automatically copy the shared libraries to a folder of your choice.

Show external IP and geolocation information.

Primary feature is the use of tee to echo IP _and_ send to geoiplookup command...Use IP as input for as many commands as you want with more >( [command] )

Requires MaxMind DB and geoiplookup tool.

Sample output has IP obfuscated on first line, lines 2-4 from having MaxMind Country && MaxMind City DBs installed

Finally, we can make the file "unchangeable"

sudo chattr +i

This variation can handle file paths containing spaces.

Kill all process that concide whit PATTERN

This is a handy command to put into ~/.bash_logout to automatically un-mount windows shares whenever the user logs out. If you use this on as a non-root account then you'll need to append sudo before umount and the user will need to have the appropriate sudoer rights to run the /bin/umount command.

Assuming you have zenity installed, and assuming that you keep your backgrounds in ~/backgrounds, then this should work for you! :)
