Get your external IP address ( 10 characters long )
Shortest url to a external IP-service, 10 characters.

Run any GUI program remotely
$ ssh -X example.org xeyes The SSH server configuration requires: X11Forwarding yes # this is default in Debian And it's convenient too: Compression delayed

ensure your ssh tunnel will always be up (add in crontab)
I find it ugly & sexy at the same time isn't it ?

Output files without comments or empty lines
Filter comments and empty lines in files. I find this very useful when trying to find what values are actually set in a very long example config file. I often set an alias for it, like : alias nocomment='grep -v "^\($\|#\)"'

Find commets in jpg files.
Finds comments in jpg files, but I can't figure out how to exclude (in output) files without comments.

nohup that doesn't generate nohup.out
I'm sure this can be piped into another way. Please share!

Mount/unmount your truecrypted file containers
This should automatically mount it to /media/truecrypt1. Further mounts will go to /media/truecrypt2, and so on. You shouldn't need sudo/su if your permissions are right. I alias tru='truecrypt' since tr and true are commands. To explicitly create a mount point do: tru volume.tc /media/foo To make sure an GUI explorer window (nautilus, et al) opens on the mounted volume, add: --explorer To see what you currently have mounted do: tru -l To dismount a volume do: tru -d volume.tc. To dismount all mounted volumes at once do: tru -d Tested with Truecrypt v6.3a / Ubuntu 9.10

Quick access to the ascii table.

Rename files in batch

Stop and continue processing on a terminal
This will send the ASCII sequence for DC3 to the currently running tty which results in SIGSTOP (19). You can continue with ASCII sequence for DC1 by pressing CTRL+q which results in SIGCONT (18).
