Problem with positional parameters (solved)

case "$1" in

  install|-i)
     PKG="$@"
     install_package ;;
   
  remove|-r)
     PKG="$@"
     remove_package ;;

esac

Problem is that -i (or -r) are picked as part of $PKG variable and I can't find solution for PKG to be $2 $3... and anything after that (not $1, because it is taken).

I hope you could understand this.

Re: Problem with positional parameters (solved)

I, for one, cannot understand. Please clearly explain what you're trying to accomplish, show us example input and ouput, etc.

As a minor rant, not to be taken personally, it's really frustrating to me when a thread opens with a code/output example with no text introducing what I'm supposed to be looking at in the example. Please provide at least a small introduction so people know what you're talking about; we can't all read minds here.

Have a look at getopts. It's in man Bash and a web search will pull up many examples.

Re: Problem with positional parameters (solved)

Thanks for your comments,

What I want is for example type:

spkg -i NAME1 NAME2 NAME3...  (spkg is script name)

and that this part "NAME1 NAME2 NAME3..." be variable PKG. Instead currently whole "-i NAME1 NAME2 NAME3... " is considered as PKG.

-i is position parameter $1 as it should, but how to avoid including it into $PKG. Something that says $2...
