csh
The "C" shell. Written by Bill Joy at Berkeley (who went on to found Sun Microsystems). Many things in common with the Bourne shell, but many enhancements to make interactive use much nicer. The syntax of the internal commands used only in scripts is very different from "sh", and is similar to the "C" programming syntax.
tcsh
The "TC" shell. Freely available, written mostly by various folks at Cornell University, and based on "csh". It has many additional features to make interactive use more convenient. The disadvantage is that until recently, it was not
installed by default on many versions of Unix. Not many people write scripts in [t]csh. We use it as the default shell for new accounts on all of our public systems.

请问怎样在tcsh中返回一个特定名称的进程的PID

KornLee

2. /home/javalee:tcsh
3. [javalee@Linux ~]$ ps
4.   PID TTY          TIME CMD
5.   553 pts/0    00:00:00 ksh
6. 1668 pts/0    00:00:00 tcsh
7. 1688 pts/0    00:00:00 ps
8. [javalee@Linux ~]$ ps|awk '/tcsh/{print $1}'
9. 1668
10. [javalee@Linux ~]$ echo $0
11. tcsh
12. [javalee@Linux ~]$
