Execute most recent command containing search string.
Execute the most recent command containing search string. This differs from !string as that only refers to the most recent command starting with search string.

rsync over ssh via non-default ssh port
tested on cygwin and Fedora 9 . good to remember for those jobs where you cannot set a site-specific connect option in your ~/.ssh/config file.

Generate RSA private key and self-signed certificate
This will create, in the current directory, a file called 'pk.pem' containing an unencrypted 2048-bit RSA private key and a file called 'cert.pem' containing a certificate signed by 'pk.pem'. The private key file will have mode 600. !!ATTENTION!! ==> this command will overwrite both files if present.

tar the current directory wihtout the absolute path
tars the current directory (and its children) in an archive of the same name (plus ".tar" :)) in the parent directory without the absolute path, so that when the archive is extracted, only the current directory name is created for the path. Assumes bash/zsh.

Command line calculator
works with fractions like 1/3.5

Incase you miss the famous 'C:\>' prompt

Show bash's function definitions you defined in .bash_profile or .bashrc
If you omit the function name, the command will display all definitions
