I'm a noob working on a script to take 3 user inputs. One of them is simply a variable: "poolname". The other 2 are cases: "groupa/groupb" and "enable/disable". "groupa" and "groupb" reference 2 files - groupa.txt or groupb.txt. These files simply consist of a list of server IP addresses and port numbers.
Based on the inputs, the script executes a command but, it needs to repeat the command once for each line in "groupa.txt" or "groupb.txt".
I've got the basics of it working, but the problem I'm having is with the loop to execute the command for each line in the list. Should I be doing this with a function or array or something else? Am I going about this all wrong? For now, I have the loop at the "group" case, but the script is not working correctly with the loop there.
Code:
!/bin/sh -x
usage() {
echo "Usage: $1 <poolname> <group_a|group_b> <enable|disable>"
}
action() {
b pool $1 member $2 session $3
}
if [ $# -ne 3 ]; then
usage $0
exit 1
fi
POOLNAME=$1
GROUP=$2
VERB=$3
case "$GROUP" in
"group_a")
GROUP=`for i in $(cat groupa.txt); do echo $i; done`
;;
"group_b")
GROUP=`for i in $(cat groupb.txt); do echo $i; done`
;;
*)
echo "Unknown action $GROUP"
esac
case "$VERB" in
"enable")
action $POOLNAME $GROUP $VERB
;;
"disable")
action $POOLNAME $GROUP $VERB
;;
*)
echo "Unknown action $VERB"
esac
