Symlink all files from a base directory to a target directory

Search for a single file and go to it
This command looks for a single file named emails.txt which is located somewhere in my home directory and cd to that directory. This command is especially helpful when the file is burried deep in the directory structure. I tested it against the bash shells in Xubuntu 8.10 and Mac OS X Leopard 10.5.6

Ping scanning without nmap
Usefull for when you don't have nmap and need to find a missing host. Pings all addresses from 10.1.1.1 to 10.1.1.254, modify for your subnet. Timeout set to 1 sec for speed, if running over a slow connection you should raise that to avoid missing replies. This will clean up the junk, leaving just the IP address: for i in {1..254}; do ping -c 1 -W 1 10.1.1.$i | grep 'from' | cut -d' ' -f 4 | tr -d ':'; done

list files recursively by size

Check the age of the filesystem
Very useful set of commands to know when your file system was created.

convert flac to mp3
if you haven't already done so, install lame and flac: sudo apt-get install lame flac

Insert a line for each n lines

How to secure delete a file
Instead, install apt-get install secure-delete and you can use: -- srm to delete file and directory on hard disk -- smem to delete file in RAM -- sfill to delete "free space" on hard disk -- sswap to delete all data from swap

Get the /dev/disk/by-id fragment for a physical drive
Substitute for #11720 Can probably be even shorter and easier.

GRUB2: set Super Mario as startup tune
I'll let Slayer handle that. Raining Blood for your pleasure.
