That's the only reason I've ever done much of anything in shell script. As a network administrator I've worked many network appliances running on some flavor of Unix and the one language I can count on to be always available is bash. It has been well worth knowing for just that reason.

I wrote a script to do backups on a ESXi it uses Busybox's ASH, one thing I learned after spending hours debugging my scripts was that ASH does not support arrays so you have to do everything with temporary files.

Only if you scripted it

I've had enough of these motherfucking scripts on this motherfucking PC!
