Check These Out

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"

Get lines count of a list of files
This command gives you the number of lines of every file in the folder and its subfolders matching the search options specified in the find command. It also gives the total amount of lines of these files. The combination of print0 and files0-from options makes the whole command simple and efficient.

Make a zip file with date/time created in the name of the file , zip all sub-directorys
zip -r /tmp/filename-`date +%Y%m%d_%H%M%S`.zip /directory/

check the status of 'dd' in progress (OS X)
"killall -USR1 dd" does not work in OS X for me. However, sending INFO instead of USR1 works.

Insert a line at the top of a text file without sed or awk or bash loops
Just use '-' to use STDIN as an additional input to 'cat'

Show log message including which files changed for a given commit in git.

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 ../../../../'

Get the 10 biggest files/folders for the current direcotry

Backup of a partition
Clone a partion with tar.
