bulk rename files with sed, one-liner
Renames all files in a directory named foo to bar. foobar1 gets renamed to barbar1 barfoo2 gets renamed to barbar2 fooobarfoo gets renamed to barobarfoo NOTE: Will break for files with spaces AND new lines AND for an empty expansion of the glob '*'

Top ten (or whatever) memory utilizing processes (with children aggregate)
This command loops over all of the processes in a system and creates an associative array in awk with the process name as the key and the sum of the RSS as the value. The associative array has the effect of summing a parent process and all of it's children. It then prints the top ten processes sorted by size.

Rapidly invoke an editor to write a long, complex, or tricky command
Next time you are using your shell, try typing ctrl-x e (that is holding control key press x and then e). The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR. Then you can edit at leisure using all the powerful macros and commands of vi, emacs, nano, or whatever.

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)

Compress blank lines

Create a single-use TCP proxy with copy to stdout
USAGE: gate listening_port host port Creates listening socket and connects to remote device at host:port. It uses pipes for connection between two sockets. Traffic which goes through pipes is wrote to stdout. I use it for debug network scripts.

Setting global redirection of STDERR to STDOUT in a script
You have a script where =ALL= STDERR should be redirected to STDIN and you don't want to add "2>&1" at the end of each command... E.G.: $ ls -al /foo/bar 2>&1 Than just add this piece of code at the beginning of your script! I hope this can help someone. :)

Greets the user appropriately

Extract title from HTML files
previous version leaves lots of blank lines

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him
