+#### 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```
