The cd "command" is built-in to whatever shell you're using. You're
right; there's no reason that I can think of that `cd pic*' above
shouldn't go ahead and do `chdir("pic22")'. The authors of tcsh (you
are using tcsh, no?) just didn't make it that way. Maybe they were
emulating old csh behavior, or maybe they just didn't think of it.
FYI, bash does something different; namely, it expands the shell
wildcards and drops all arguments but the first to cd. So, in your
case above `cd pic22*' does what you expect, but only because pic22
comes before pic22.tgz when the '*' is expanded.
HTH,
