Pattern: Redundant getopts
flag
Issue: -
You have a case
statement in a while getopts
loop that matches a flag that hasn't been provided in the getopts
option string.
Either add the flag to the options list, or delete the case statement.
Example of incorrect code:
while getopts "vr" n
do
case "$n" in
v) echo "Verbose" ;;
r) echo "Recursive" ;;
n) echo "Dry-run" ;;
*) usage;;
esac
done
Example of correct code:
while getopts "vrn" n # 'n' added here
do
case "$n" in
v) echo "Verbose" ;;
r) echo "Recursive" ;;
n) echo "Dry-run" ;;
*) usage;;
esac
done
