Variable from a text file
I have a variable from a txt file, can i create more variables from the same txt file?
Code:
diffs.txt
device for 0117bd1: lpd://172.25.29.60:515
device for 2001bl7: socket://172.25.44.188:9100
device for 2201bl7: socket://172.25.11.170:9100
device for 5001bl1: lpd://172.25.11.203:515

Code:
printer_list="$(awk -F: '{print $1 }' diffs.txt | cut -c11-18)"

i want to create three others from the same text file, with
LPD,
IP Address and
PORT
