I need to read command line argument which is passing as scriptname –c "30,31,32,33,34,35"
and convert it to
myArray=( 30 31 32 )
Try the following:
while getopts c: option
do
case $option in
c) data="$OPTARG"
;;
esac
done
oldIFS="$IFS"
IFS=','
myArray=($data)
IFS="$oldIFS"
echo ${myArray[@]}
The c: after getoptsindicates that we have an option -c, the : indicates it is followed by an argument, which is retrieved using $OPTARG.
IFS if the Inter Field Separator which I reset to a comma in order to create the array.
