I check two cases and throw out a regular expression which will die in the particular cases game). A nice thing I discovered recently are the shortcut keys you can use:
- Ctrl + A
- Go to the beginning of the line you are currently typing on
- Ctrl + E
- Go to the end of the line you are currently typing on
- Ctrl + L
- Clears the Screen, similar to the clear command
- Ctrl + U
- Clears the line before the cursor position. If you are at the end of the line, clears the entire line.
- Ctrl + H
- Same as backspace
- Ctrl + R

- Ctrl + C
- Kill whatever you are running – proably a well known to everyone
- Ctrl + D

- Ctrl + W
- Delete the word before the cursor
- Ctrl + K
- Clear the line after the cursor
- Ctrl + T
- Swap the last two characters before the cursor
- Esc + T
