underline() will print $1, followed by a series of '=' characters the width of $1. An optional second argument can be used to replace '=' with a given character.

This function is useful for breaking lots of data emitted in a for loop into sections which are easier to parse visually. Let's say that 'xxxx' is a very common pattern occurring in a group of CSV files.

You could run

This would print the name of each csv file before each matching line, but the output would be hard to parse visually.

Will break the output into sections separated by the name of the file, underlined.

For those who hate navigating info pages, a shell function which will dump the contents to stdout, then page it through less, thus acting like 'man'.

Like command #4845, prints score, number of entries, and average score.

given lines of the form

123|XXXX|1000

...

123|XXXX|1011

each 'XXXX' will be replaced with a serial number between 0001 and 0004.

This replaces the current bash session with a new bash session, run as an interactive non-login shell... useful if you have changed /etc/bash.bashrc, or ~/.bashrc

If you have changed a startup script for login shells, use

Suitable for re-running /etc/profile, ~/.bash_login and ~/.profile.

edit: chinmaya points out that

will clear any shell variables which have been set... since this verges on unwieldy, might want to use

The function will take a comma separated list of items to be 'selected' by xsel -i:

You will then be prompted to choose one of the menu items. After you choose, you will be able to paste the string by clicking the middle mouse button.

The menu will keep prompting you to choose menu items until you break out with Control-C.

Set up X forwarding in PuTTY, with X display location set to :0.0

Each shell function has its own summary line, as a comment. If there are multiple shell functions with the same name, the function with the highest number of votes is put into the file.

Note: added 'grep -v' to the end of the pipeline, to eliminate extraneous lines containing only '--'. Thanks to matthewbauer for pointing this out.

the 'set -x' mode can be exited by typing

This is useful when you're diffing two files of the same name in radically different directory trees. For example:

Set

then

then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.

Creates a directory named with the current date, in the format YYYYMMDD. If you give it a directory name as an argument, it will create the new directory inside the specified directory.

This is an alternative to command #1993.

for example:

yields

1234567

This version of tweet() doesn't require you to put quotes around the body of your tweet... it also prompts you for password. It will still barf on a '!' character.
