The C Shell is very useful and powerful in its own right, but there are other Shells that add functionality that can make working in the Unix environment more enjoyable. In this section, we will discuss two popular Unix Shells briefly, and highlight a few of the differences between them. After the C Shell was introduced, there was an effort to fix many of the bugs in it , cited: [(Unix Shell Programming )] [Author: Stephen G.

Using a shell like C shell which has ``job-control'' you can actually start jobs in addition to your login job.
