Check These Out

Iterate through current directory + all subs for C++ header files and rank by # of comments
This shows you which files are most in need of commenting (one line of output per file)

list files recursively by size

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Remove all .svn folders

check open ports without netstat or lsof

Search inside a folder of jar/zip files
Great for finding which jar some pesky class is hiding in!

move you up one directory quickly
Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../'

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Create a new file

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
