Create full backups of individual folders using find and tar-gzip
Problem: I wanted to backup user data individually. In this example, all user data is located in "/mnt/storage/profiles", and about 25 folders inside, each with a username ( /mnt/storage/profiles/mike; /mnt/storage/profiles/lucy ...) I need each individual folder backed up, not the whole "/mnt/storage/profiles". So, using find while excluding directories depth and creating two variables (tarfile=username & desdir=destination), tar will create a .tgz file for each folder, resulting in a "mike_full.tgz" and "lucy_full.tgz".

ssh from local to remote and pipe output of file to the local clipboard

ssh -A user@somehost

Start another X session in a window
You might have Xnest (older) rather than Xephyr. You can experiment with other desktops eg: startx /usr/bin/start-kde -- /usr/bin/Xephyr :2 You can start X on a remote machine (although I'd recommend vnc for anything slower than a LAN): startx /usr/bin/ssh -X gnome-session -- /usr/bin/Xephyr :2 Or just start another X session locally talking to the remote backend:

Who invoked me? / Get parent command
Get the name of the parent command. This might be helpful, if you need to react on that information. E. g. a script called directly via ssh has got sshd as parent, manually invoked the parent process will probably be bash

en/decrypts files in a specific directory
To decrypt the files replace "ccenrypt" with "ccdecrypt. ccrypt(1) must be installed. It uses the AES (Rijndael) block cipher. To make it handier create an alias.

Replicate a directory structure dropping the files
Here is how to replicate the directory structure in the current directory to a destination directory (given by the variable DESTDIR), without copying the files.

Which processes are listening on a specific port (e.g. port 80)
