Doubt in getopts commands

Shell Programming and Scripting

I am new to getopts command. I wonder the if there is any built in way to detect that if both options occurred from [ a | b] where only on them is expected.

command [-a | -b]

Correct
command -a
command -b

Incorrect
command -a -b
command -ab

Please clarify my doubt.

Hi tamil.pamaran,

What about checking them after getopts loop?

if [[ -n "$aflag" ]] && [[ -n "$bflag" ]]; then
    echo "Incorrect"
    exit 1
fi

Regards,
Birei

I don't think getopts is that flexible. Lets wait for others response too.

No it doesnt...as birei noted you will have to check after getopts has parsed the command line arguments.
