Is mixing getopts with positional parameters possible?

Question

I want to design a shell script as a wrapper for a couple of scripts. I would like to specify parameters for myshell.sh using getopts and pass the remaining parameters in the same order to the script specified.

If myshell.sh is executed like:

myshell.sh -h hostname -s test.sh -d waittime param1 param2 param3  myshell.sh param1 param2 -h hostname param3 -d waittime -s test.sh  myshell.sh param1 -h hostname -d waittime -s test.sh param2 param3 

All of the above should be able to call as

test.sh param1 param2 param3 

Is it possible to utilize the options parameters in the myshell.sh and post remaining parameters to underlying script?

Answer 1

I wanted to do something similar to the OP, and I found the relevant information I required here and here

Essentially if you want to do something like:

script.sh [options] ARG1 ARG2 

Then get your options like this:

while getopts "h:u:p:d:" flag; do case "$flag" in     h) HOSTNAME=$OPTARG;;     u) USERNAME=$OPTARG;;     p) PASSWORD=$OPTARG;;     d) DATABASE=$OPTARG;; esac done 

And then you can get your positional arguments like this:

ARG1=${@:$OPTIND:1} ARG2=${@:$OPTIND+1:1} 

More information and details are available through the link above.

Hope that helps!!
