Check These Out

Two command output
Summarize established connections after netstat output. Using tee and /dev/stderr you can send one command output to terminal before executing wc so you can summarize at the bottom of the output.

Command line calculator
This opens a python command line. You can use math and random and float-division is enabled (without appending .0 to integers). I just don't know how to specify a standard precision.

Complex string encoding with sed
Pipe | avoid escaping occurences problems in using sed and make it easier to use

search user defined function in c language

Protect your eye
Redshift will adjust the color temperature and protects eye at night -b : will adjust the brightness

Get line number of all matches in a file

Get the canonical, absolute path given a relative and/or noncanonical path
readlink -f accepts a relative, noncanonical path and emits the corresponding canonical, absolute path.

Search google and show only urls
Get the first 10 google results form a querry, but showing only the urls from the results. Use + to search diferent terms, ex: commandlinefu+google .

Reset hosed terminal,
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.

Create a bunch of dummy files for testing
Sometimes I need to create a directory of files to operate on to test out some commandlinefu I am cooking up. The main thing is the range ({1..N}) expansion.
