Question

So, I’m trying my hand at using bash’s built-in getopts to handle argument processing except I’m getting a strange result. Here’s my test script;

#!/bin/sh

HOST=
OWNER=
GROUP=

while getopts "h:o:g" OPTION;
  do
    case $OPTION in
    h)
      HOST=$OPTARG
      ;;
    o)
      OWNER=$OPTARG
      ;;
    g)
      GROUP=$OPTARG
      ;;
  esac
done

echo "$HOST - $OWNER:$GROUP"

Yet, when I run the script using this;

./test.sh -h test.host.com -o skittles -g whatever

My last arg never gets pulled in or is getting dropped. My result from the echo is;

test.host.com - skittles:
                         ^ where's my group value? O.o

Does anyone know what would be causing this?

Thanks.

Answer 1

It seems your expect -g to have an argument, but in your options declaration, there is no “:” related to your -g.

You should have this:

h:o:g:
