  • From time to time one forgets either thier gpg key or other passphrases. This can be very problematic in most cases. But luckily there's this script. Its based off of pwsafe which is a unix commandline program that manages encrypted password databases. For more info on pwsafe visit, http://nsd.dyndns.org/pwsafe/. What this script does is it will help you store all your passphrases for later on and allow you to copy it to your clipboard so you can just paste it in, all with one password. Pretty neat no? You can find future releases of this and many more scripts at The Teachings of Master Denzuko - denzuko.wordpress.com. Show Sample Output

  • While I love gpg and truecrypt there's some times when you just want to edit a file and not worry about keys or having to deal needing extra software on hand. Thus, you can use vim's encrypted file format. For more info on vim's encrypted files visit: http://www.vim.org/htmldoc/editing.html#encryption Show Sample Output

    vim -x <FILENAME>

  • This is the alias command that I discussed in my prior release which you can add to your ~/.bashrc. This command asks for the station name and then connects to somafm, Great for those who have linux home entertainment boxes and ssh enabled on them, just for the CLI fiends out there ( I know I'm one of them ;) You can find future releases of this and many more scripts at the teachings of master denzuko - denzuko.co.cc.

Check These Out

Export unpushed files list

Continue a current job in the background
Continue a current job in the background and detach it from current terminal

Show tcp connections sorted by Host / Most connections

delete all trailing whitespace from each line in file

Pick a random line from a file

List programs with open ports and connections
I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

Rename files in batch

Safe Russian Roulette (only echo, don't delete files)
Shows "Bang!" in a chance of 1 out of 6, like in the original game with the gun (spin every round). Otherwise, echoes "Click...". If feeling brave you can also do: $[ $[ $RANDOM % 6 ] == 0 ] && echo 'Bang!' && a really killer command || echo 'Click...'

check open ports without netstat or lsof

shush MOTD
I'm annoyed by the boilerplate "don't login unless you are supposed messages in our environment" - this shuts them up.
