Show local/public IP adresses with or without interface argument using a shell function for Linux and MacOsX
Like the tiltle said, you can use an argument too ( the interface ) $ MyIps eth0 will show only the IP of this interface and the public IP ( tested with Linux ) You can add that function in ~/.bashrc, then $ . ~/.bashrc Now you are ready to call this function in all your terms...

Bash Dialog
The dialog utility is used to create a basic level graphical user interface. We can use this in Shell script to create very useful programs.

suspend to ram without root
$dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend

display a smiling smiley if the command succeeded and a sad smiley if the command failed
you could save the code between if and fi to a shell script named smiley.sh with the first argument as and then do a smiley.sh to see if the command succeeded. a bit needless but who cares ;)

Output sound when your computer is downloading something
Outputs pseudo-random sounds to speakers (stereo mode because of -c 2) when there are any kind of network activity.

diff will usually only take one file from STDIN. This is a method to take the result of two streams and compare with diff. The example I use to compare two iTunes libraries but it is generally applicable.
diff is designed to compare two files. You can also compare directories. In this form, bash uses 'process substitution' in place of a file as an input to diff. Each input to diff can be filtered as you choose. I use find and egrep to select the files to compare.

Poor man's ntpdate
If you don't have netcat, you can use curl.

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

check open ports without netstat or lsof
