Return code of a shell script

zachos.v · 10-06-2006, 06:04 AM

when I run a shell script I always get as return code -1. (Even if the script run successful.)

I test it with one line script just
cp $1 $2

I am using kernel 2.6.9-11.ELsmp (RED Had).
Any Ideas

Thanks

Unlikely ...

Even more unlikely, can you post the commands your run to execute the script and show its return value ?
There must be something wrong, as a shell script return value is between 0 and 255.

you are right

Let me explain a bit more...
The script is copy a file from one location to another and then A program is processing the file. What I want is to check if the copy was successful or not.
To do that I check the return code of the script. If is 0 then the cp was successful if is any other value I return error.
this was running successful for RED HAD advance server 2.1. If I run that application to RED HAD advance server 4.1 I receive the value 1 (not -1

) from the script even if the cp was successful!

Better post the script instead.
