Extract icons from windows exe/dll

move cursor to beginning of command line
Pressing Ctrl combined with 'a' will move the cursor to the beginning of the command under bash (other shells?). I used to do this after arrowing up for the last command, then typing 'sudo ' to run the last command as root, but of course the all time greatest command here `sudo !!` is more succinct. Still Ctrl+A can be very useful when you want to edit something at/close to the beginning of the command line.

list files recursively by size

Realtime lines per second in a log file
Using tail to follow and standard perl to count and print the lps when lines are written to the logfile.

Broadcast your shell thru ports 5000, 5001, 5002 ...
run 'nc yourip 5000', 'nc yourip 5001' or 'nc yourip 5002' elsewhere will produce an exact same mirror of your shell. This is handy when you want to show someone else some amazing stuff in your shell without giving them control over it.

sum numbers in the file (or stdin)
add integers from the stdin and print out the result usually, cat /tmp/file | echo $(($(tr '\n' '+')0))

List all files opened by a particular command
List all file opened by a particular command based on it's command name.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

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"
