shell is a bit like JavaScript: both languages have a lot of warts, but if you interact with UNIX-like systems / browsers at intermediate or above levels, you must be comfortable with them. Unlike browsers, you have a few choices for shells, and IMHO [t]csh lost because a) Linux "won" over *BSDs, b) POSIX basically standardized on sh, c) [t]csh is a worse scripting language. Back in uni I used to use tcsh interactively, script in [ba]sh, and program in a "real language" like C, Java, etc., but I wasn't doing anything very complicated with any of them. Once I started working and begin using these tools seriously, I simply couldn't learn and retain all of them. Something had to go, and tcsh was it.
