Depends on platform. In the commercial realm (i.e. Solaris and HP-UX), 
Korn shell is wildy used/useful. I prefer ksh on Solaris. AIX, I forget.

With free OS's (*BSD, Linux), Bourne shell (sh) is the most wildly used 
(for startup, system scripts, etc.). But tcsh is root's default install 
on FreeBSD. tcsh is a big improvement of C shell (csh). On Linux and 
FreeBSD (as a regular user), Bourne Again shell (bash) seems to be the 
most popular.

For portability, the safest is to script in Bourne shell (sh). ksh, 
pdksh, and bash, all can run Bourne shell (sh) scripts. Plus there's the 
benefit of running on older OS and cross platform. And tcsh can run csh 
scripts, if you're more familiar with csh.
