Data RE: exit value
I am running HP-UX & ksh

I have several validation programs that scan log files for error messages.

One of these files scan 3 diff files, thus I have the exit value in a variable and depending on which log-file I am scanning the value changes.
I am not getting the value I expect but a different value ( echo $? displays 213 - expect -777).
So my question is: Can you exit with a variable instead of a fixed value?

exit $xerr (where xerr=-777)
vs.
exit -777

THX in advance. Smilie

The exit value should be larger than what can be represented in eight bits: 0-127 signed or 0-255 unsigned.
Stick with numbers like 101, 102, 103

This is because unix wait strips all but the lowest eight bits from the return code before passing it to "$?"

Exit or logout

When I want to close my session I can use exit or logout, and a lot of manuals use both of them indistinctly. So, Is there any difference between exit or logout?? Or are both of them exactly the same command?? I forgot to mention that I am using a RedHat Unix. Thanks for your help. Kinai. (1 Reply)
