AWK: Set Field Separator from command line

Create a tar of directory structure only
The original suggestion did not work for me, when operating on folders located on an external mount (ie other than the root device) in Ubuntu. A variation using xargs does the trick.

output your microphone to a remote computer's speaker
This will output the sound from your microphone port to the ssh target computer's speaker port. The sound quality is very bad, so you will hear a lot of hissing.

Get a list of all TODO/FIXME tasks left to be done in your project
Place this in your .bashrc (or run it once) to set the `tasks` alias. Next time you enter `tasks` into a terminal, it will give you a list of all TODO and FIXME comments in the current directory and child directories, giving you a quick overview of what you still have to do!

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

display ip address
add this alias in .bashrc to fast check the ip address of your modem router alias myip="curl -s http://myip.dk | grep '' | sed -e 's/]*>//g'"

Get your local IP regardless of your network interface
Shows only IP-addresses of ifconfig except 127.0.0.0/8. I fixed the script to work on more systems and configs short info /inet/!d; #grep inet /127.0/d; # grep -v 127.0 /dr:\s/d; # grep -v dr: s/^.*:\(.*\)B.*$/\1/ # remove everything exept between : and B

Right-align text in console using pipe like ( command | right )

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"

Join lines
It's works only when you replace '\n' to ONE character.
