Re: How to suppress warning messages for empty lines in shell scripts?

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

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?

You don't have to avoid blank lines.
Are you sure they're really blank?
Try "cat -A /usr/local/joch/bin/dotest" to see if you've got some unprintable characters in your lines.
