Unmatched SSID & password












0














I'm working on script which will be use for connecting to wifi.

Specification:

- Don't use network-manager.

- Some SSID & Password is stored in file.

- If SSID is matched than get the password from file & connect to wifi.

- File format is like this:



SSID:CoreFragment
Passphrase:WiFi1234
SSID:CoreFragment_5G
Passphrase:WiFi1234
SSID:Aleph_inCar
Passphrase:1234567890


Function for searching SSID:



search_ssid(){
sudo service network-manager stop
rfkill unblock wifi
sudo ifconfig wlp2s0 up
sudo iwlist wlp2s0 scan | grep SSID
for ssid_name in $(sudo iwlist scan 2>/dev/null |grep ESSID | sed 's/.*ESSID:"(.*)".*/1/')
do
echo "$ssid_name";
done
}


Here is my function for getting SSID and passphrase:



ssid_password(){
ssid=$(grep -oP '^SSID:K.+' list_wifi.txt)
for ssid in $(grep -oP '^SSID:K.+' list_wifi.txt)
do
if [ $ssid == $ssid_name ]; then
echo "SSID found...";
passphrase=$(awk '/Passphrase/ && match($0,/CoreFragment Passphrase:[0-9a-zA-Z]+/){val=substr($0,RSTART,RLENGTH);sub(/.*:/,"",val);print val;val=""}' list_wifi.txt)
echo "$passphrase";
fi
done
}


There is 3 problems:

1) ssid_password is not working properly.

2) getting passphrase from file is also not working.

3) passphrase not printing(blank line in output).

Where is the problem in my function?

I'm working on ubuntu 18.04
