Description Cai Xianchao 2008-03-05 02:48:27 EST
Description of problem:

The manpage says that "command must  be  a  simple  command,  not  an alias,  a
 pipeline,  a command list or a parenthesized command list, but it  may  have 
arguments.", but "command" can be a command list.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.[test@localhost ~]$ ls

2.[test@localhost ~]$ pwd

3.[test@localhost ~]$ if (1) ls;pwd

Actual results:
The command 'ls' and 'pwd' both are executed correctly.

Expected results:
There is a error outputed or only one command is executed.

Comment 2 Vitezslav Crhonek 2008-03-05 06:16:32 EST

[test@localhost ~]$ if (0) ls;pwd

The second command does have nothing to do with the 'if' statement.
Comment 3 Cai Xianchao 2008-03-05 19:56:35 EST
I see.

The tcsh regards 'if (0) ls;pwd' as two commands, 'if (0) ls' and 'pwd'.

Actually, when I saw something like 'command must  be  a  simple  command', I
thought it would fail and the exit code would be not 0 if 'command is not a
simple command'. 

Thanks for your example.
