Bash script - how to read file line by line while using getopts
getopts only parses options (arguments starting with -); the other arguments are left alone. The parameter OPTIND tells you the index of the first argument not yet looked at; typically you discard the options before this.

$ bash tmp.bash -a -b c d ea is enabledb is enabled3 arguments remaining:cde
