#### Shell Tricks &nbsp;[<sup>[TOC]</sup>](#anger-table-of-contents)
When you get a shell, it is generally not very clean, but after following these steps, you will have a fairly clean and comfortable shell to work with.
1) `script /dev/null -c bash`
2) Ctrl-Z (to send it to background)
3) `stty raw -echo; fg` (returns the shell to foreground)
4) `reset` (to reset terminal)
5) `xterm` (when asked for terminal type)
6) `export TERM=xterm; export SHELL=bash`
