function verify
{
if [ $# -ne 2 ]
then echo "Wrong number of arguments!"
else if [ $1 -eq Bob ] && [ $2 -eq 555 ]

else echo "Rejected"
fi
fi
}
export verify
subprogram1

[ $1 -eq Bob ]

function verify { if [[ $# -ne 2 ]]; then echo 'Wrong number of arguments!'; elif [[ $1 == 'Bob' && $2 -eq 555 ]]; then echo 'Verified'; else echo 'Rejected'; fi }
verify a 111
Rejected
verify a
Wrong number of arguments!
verify Bob 555
Verified
