echo $? returning 13432 in bash on linux

[Scunningham99]

After running a simple script which does a simple echo command. Intermit. getting weird number when expecting 0

ie

echo $?
13264 <-- this number not always the same random??

then Occasionally get a 0. Any ideas?

When we put shell back to ksh we dont get this?

Did you run another command before the "[tt]echo $?[/tt]"? If that command had a non-zero return code, it would display that.

Hi

SamBones, that not happens to me :

[blue]master #[/blue] ( exit 13264; )
[blue]master #[/blue] echo $?
208

And as I understand, it neither should.

Within a script, an exit nnn command may be used to deliver an nnn exit status to the shell (nnn must be a decimal number in the 0 - 255 range).

( Advanced Bash-Scripting Guide | Exit and Exit Status )

[gray](...)[/gray] the status value is truncated to eight bits. Thus, if the program tried to report 256 errors, the parent would receive a report of 0 errors—that is, success.

That doesn't explain why Scunningham99 is getting seemingly random values that are over 255.

Hi

Right. I just tried to point out that answering your "Did you run another command before" question would not lead to the root of problem.

hi

no echo is the last command??

So, the whole script is only the echo command ?
If this is the case then I'd insert a dummy command:

true
echo $?

Otherwise, please post the code

Hope This Helps, PH.

Yeah, time to see some code. Also, could you post the output of these commands?

bash --version
uname -a
