break statement not woking in shell script












0















Here is a part of code:



ssid_password(){
ssid=($(grep -oP '^SSID:K.+' list_wifi.txt))
ssid_search=($(sudo iwlist wlp2s0 scan | grep ESSID | cut -d '"' -f2))
for ssid_search in "${ssid_search[@]}"
do
for ssid in "${ssid[@]}"
do
if [ $ssid == $ssid_search ]; then
echo "SSID match...";
# echo "$ssid";
# passphrase=$(awk -F: -v s="$ssid_search" '$0=="SSID:"s{c=NR+1} c==NR{print $2; exit}' list_wifi.txt)
# echo "$passphrase";
break
fi
# break
done
done
}

ssid_password


In this function if match found it should come out of the loop. For that I've used break statement in shell script.

But it is not working,It search for all.
