getopts with repeat of same option
Hello,
Does getopts have some way of handling the use of an option that requires a parameter more than once on the command line.
e.g. mycmd -a john -a jane
I came up with a solution using arrays (shown below), but wonder if getopts has some other way of handling it. Other solutions welcome.
Code:
 x=1
 while getopts a:b OPTION
 do
   case $OPTION in
      a) AA[$x]=$OPTARG ;;
      b) true
   esac
   x=$((x+1))
 done

Thank you

We have some old code that concatenates like this
Code:
x=1
 while getopts a:b OPTION
 do
   case $OPTION in
      a) AA="$AA $OPTARG" ;;
      b) true
   esac
 done

you should move your x+1 up and make another change or two, maybe.
Code:
x=0  # arrays count from zero
 while getopts a:b OPTION
 do
   case $OPTION in
      a) AA[$x]=$OPTARG; x=$((x+1))  ;;
      b) BB="true" ;;
   esac
 done

Thanks Jim,
Your first option worked fine, and made it easier for me to convert the info into an array in awk (with the split function) which was my goal.
