Question

I found this small shell script in a book… NGiNX works it just this script that just does not work. Because every time I do /etc/init.d/nginx start (that is where the file is) it sends me this message: Usage: /etc/init.d/nginx {start|stop|restart|reload}

For testing purposes I added a echo “$1” and it sends me -e when I do: /etc/init.d/nginx start Or anything else…

I am using Ubuntu 12.04.

Answer 1

set –e is setting the list of arguments to the script to –e. Remove that line and the script will work.

Edit: The script posted contains set –e (that is EN DASH + e) as opposed to set -e (ASCII hyphen/minus sign + e). This caused sh to override the first argument passed with –e instead of setting the -e option in the shell. Replacing – with - should fix the problem.
