Tcsh

CSH is the default shell for root user on FreeBSD system. Basic usage is pretty much the same as any other shell like bash, zsh, fish or whatever. Until you try to execute some bash specific for loops, or attempt to use Delete key. Whaaaat? - Yes, apparently delete doesn’t give the correct character in csh and just prints ~. I don’t know if that’s xterm (or xterm compatible) terminal thing or just a csh thing but it doesn’t matter....
