Checking Exit Status
I hope one of you smart people out there can help me with what seems like a real simple questing but I can't quite figure out.
In a script I am doing a cmp on two files. I am trying to check the exit status with an if statement but can't seem to figure out the syntax. If the exit status is 1 I want to do something else something else. I am using Solaris 8 and my shell is ksh.

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
thank you! (9 Replies)

ZDIFF(1) General Commands Manual ZDIFF(1)
NAME
zcmp, zdiff - compare compressed files
SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ]
zdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
Zcmp and zdiff are used to invoke the cmp or the diff program on files compressed via gzip. All options specified are passed directly to
cmp or diff. If only one file is specified, then it is compared to a file with the same name without the .gz extension. If two files are
specified, then they are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved.
When both files must be uncompressed before comparison, the second is uncompressed to /tmp. In all other cases, zdiff and zcmp use only a
pipe.
SEE ALSO
cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)
BUGS
Messages from the cmp or diff programs refer to temporary filenames instead of those specified.
