I normally add a new user in squid with this command
touch /etc/squid/squid_access; htpasswd /etc/squid/squid_access "NEWuser"
then it prompts me to input the password for "newuser" and conirm it again.
How can I automate this so that I add a range of new users(user1-user500) with the same or password?
You might get what you want with the seq
command, on which youu can perform a loop in bash. You might get what you want with this or something similar:
#!/bin/sh
touch /etc/squid/squid_access
for i in $(seq 1 500)
do
htpasswd /etc/squid/squid_access "new-user-$i"
done
