The problem script
testcmd.ksh
#!/usr/bin/ksh
while getopts "d: m s z a b " opt; do
echo $opt
case $opt in
d ) echo "d" ;;
m ) echo "mail";;
s ) echo "snmp";;
z ) echo "force:";;
a ) echo "fs";;
b ) echo "bypass";;
? ) echo "Usage: [-m] [-s] [-z] ";
exit 4 ;;
esac
done
if i run the above script as "./testcmd.ksh -a", it gives
./testcmd.ksh: -a: unknown option
?
Usage: [-m] [-s] [-z]
The output I was expecting was something like this
a
fs
What could be the problem?
If I change the shebang to "#!/usr/bin/bash", it works as expected.
But, I have to use "#!/usr/bin/ksh" only.
What is the change I should do? I am using CentOs 7.
Could someone please advise?
