From the command line I called (with nohup) a shell script which contains
empty lines

The nohup executes the script successfully but outputs a warning for the
empty line:
/usr/local/joch/bin/dotest: line 3:
: command not found
How can I suppress this warning (of cause without removing the empty line)?
Do I really have to always avoid empty lines in shell scripts?
No, empty lines are fine in shell scripts.
I suspect what you actually have a are CR LF pairs as newlines, instead
of just LF, because you wrote the file on a Windows machine and
transferred it to Unix. Use dos2unix to fix it.
