Make changes in .bashrc immediately available

Determine if a port is open with bash
For times when netcat isn't available. Will throw a Connection refused message if a port is closed. Scriptable: $ (: /dev/null && echo "OPEN" || echo "CLOSED"

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

grep -v with multiple patterns.
If you wanted to do all in one command, you could go w/ sed instead

To find which host made maximum number of specific tcp connections
This command is primarily going to work on linux boxes. and needs to be changed, for example IP=10\.194\.194\.2 PORT=389

bash or tcsh redirect both to stdout and to a file
When plumbers use pipes, they sometimes need a T-joint. The Unix equivalent to this is 'tee'. The -a flag tells 'tee' to append to the file, rather than clobbering it. Tested on bash and tcsh.

Sync the existing directory structure to destination, without transferring any files

Function to add a shebang to an existing script, handy if you forgot to add it in the first place.
