I don't know what causes the error.

This:
Code:
+ + wc -c
+ cat /opt/manu/srv/manumgrmdip2_7600.log
f1size=0

shows the file does exist and you have the necessary access rights. However it's an empty file.

If the file doesn't exist or you dont have the access rights, the "cat" command would already have caused an error.

Is there another process active which could have removed the log file?

There is no other process that is removing the file. Both files are still there after this script runs.

Only other thing I can think of then is that mailx on your Unix/Linux version doesn't know hot to handle an input redirect of an empty file.

Do you get the same error if you create:

/opt/manu/srv/manumgrmdip2_7600.log with a size GREATER 0
/opt/manu/srv/manumgrmdip2_7600.pid with a size GREATER 6

I just figured it out. The problem was that I was trying to use the text of the file as the email message body (user@xyz.com < ${f1}) and it was having problems finding the file in another directory when I wasn't telling it where to look. My bad!

Thanks for ALL your help.
