Check These Out

Scan for [samba|lanman] NetBIOS names and ip addresses in LAN by ARP.

100% rollback files to a specific revision

find geographical location of an ip address
a shorter version

check open ports (both ipv4 and ipv6)
While `lsof` will work, why not use the tool designed explicitly for this job? (If not run as root, you will only see the names of PID you own)

Averaging columns of numbers
This example calculates the averages of column one and column two of "file.dat". It can be easily modified if other columns are to be averaged.

Count number of files in subdirectories
For each directory from the current one, list the counts of files in each of these directories. Change the -maxdepth to drill down further through directories.

Show sorted list of files with sizes more than 1MB in the current dir
no fancy grep stuff here.

Rename files with vim.
Opens a list of files in a text editor. Using Vim as your default editor allows you to use the power of regex substitution and visual block mode to batch rename files. Found in the renameutils package sudo apt-get install renameutils

show where symlinks are pointing
displays the output of ls -l without the rest of the crud. pretty simple but useful.

rename files according to file with colums of corresponding names
Maybe simpler, but again, don't know how it will work with space in filename.
