Subject: .sh & getopts
Have this code
shift; while getopts :ugr: arg; do case ${arg} in
u) action="freebsd-update";;
g) action="freebsd-upgrade";;
r) action="freebsd-rollback";;
?) exerr ${cmd_usage};;
esac; done; shift $(( ${OPTION} -1 ))
Command being executed looks like this, cmd action -flags aaaa bbbb
Only a single -flag in allowed on the command.
$# gives a count of parms ie: aaaa bbbb. in this example a count of 2.
I am looking for something to check that holds the number of flags on
the command. so I can code. if flag_count gt 1 = error
Is there such a thing created by getopts?
Why bother??
flag_count=0
shift; while getopts :ugr: arg
if flag_count = 1; then
exerr ${cmd_usage}
fi
flag_count=1;
do case ${arg} in
{{blah-blah}}
nope dont work.
If the flags are counted at all it has to be a function of getopts
