Is there a way to have a string as a switch using getopts?

I am seeing if there is a way for getopts to handle switches with strings instead of characters.

For example, I would like to supply something like this:

script.ksh -file1 file1.txt -file2.txt

Instead of:

script.ksh -f file1.txt -g file2.txt

Is this possible with unix getopts?

The external getopt (note no "s") can handle long options, but it has its own disadvantages.

From BashFAQ/035:

Never use getopt(1). getopt cannot handle empty arguments strings, or arguments with embedded whitespace. Please forget that it ever existed.

No, it's not possible with getopts. You must do your own parsing, e.g. with a case switch:

while (($# > 0))
do
    case "$1" in
    -file1)
        shift
        file1=$1;;
    -file2)
        shift
        file2=$1;;
    esac
    shift
done
