I'm a pragmatist. There's a delicate balance between a really bare install, and an install where just a little bit more can make a difference in productivity. The difference between being punished at the command line, or having what you need to 'get around'. Depends upon what The Install Guy says I get to have. He thinks that because I don't know vi very well I'll never be a good sysadmin.
C shell has a punitive feel to it, and has a tendency to cascade errors.
For example, if you don't set up the C shell environment prooperly, the shell in its barest configuration will reject backspacing at the command line. Retrieving commands from history requires extra keystrokes, slowing me down. Frankly, the prospect of doing anything looks like it's going to be really tedious at the command line, even if you can type fast. Simply having something like Midnite Commander ready to go would alleviate the tedium and the arcaneness. Funny how Novell or MS products never shipped with vi.
