Check These Out

Use find to get around Argument list too long problem
Can be used for other commands as well, replace rm with ls. It is easy to make this shorter but if the filenames involved have spaces, you will need to do use find's "-print0" option in conjunction with xargs's "-0" option. Otherwise the shell that xargs uses to execute the "rm" command line will treat the space as a token separator, thereby treating the name as two (or more) names.

Create several copies of a file
Copy a file to a range of other files.

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"

Generate a graph of package dependencies
Requires: imagemagick and graphviz On Debian systems, displays a graph of package dependencies. Works also with other image formats, like svg : $ apt-cache dotty bash | dot -T svg | display

Perl oneliner to print access rights in octal format
This prints file access rights in octal - useful when "stat" is unavailable.

Get your external IP address if your machine has a DNS entry
Using DynDNS or a similar service not only allows access to your home machine from outside without needing to know what IP the ISP has assigned to it but it also comes in handy if you want to know your external IP address. The only purpose of the sed command is to remove the leading "host.na.me has address " part from the output. If you don't need to discard it you can simply use $ host $HOSTNAME

Uniformly correct filenames in a directory
Useful if non-ascii characters in filenames have been improperly encoded. Replace "PROBLEM" with the incorrect characters (e.g. 'é'), and "FIX" with the correct ones (e.g. '?').

Edit 2 or more files in vim using vim -d
Use vim's diff mode to edit two or more files in one window. The '+diffoff!' turns off diff highlighting when the session is started. Use ctrl+w + ctrl+w to switch between windows.

list block devices
Shows all block devices in a tree with descruptions of what they are.

get you public ip address
