different ips in different terminal with torify

Question

how can we get a different tor circuit with torify command in a separate terminal window? Specifically, if I type a command in a terminal 1 window

torify curl http://icanhazip.com

I receive my IP address in response.

but if I try it in another terminal window simultaneously I get the same IP which is a normal behavior.

what I am trying to achieve is to use a different config file in every new terminal window so as to get a different IP address in a different terminal window.

Use the -i (--isolate) option or --user and --pass to get stream isolation.

From man 1 torsocks:

-u, --user
      Set username for the SOCKS5 authentication. Use for circuit isolation in Tor.
      Note that you MUST have a password set either by the command line,
      environment variable or configuration file (torsocks.conf(5).

-p, --pass
      Set  password  for the SOCKS5 authentication. Use for circuit isolation in
      Tor.  Note that you MUST have a username set either by the command line,
      environment variable or configuration file (torsocks.conf(5)).

-i, --isolate                                                                                                                                                                          
      Automatic tor isolation. Set the username and password for
      the SOCKS5 authentication method to a PID/current time based value
     automatically. Username and Password MUST NOT be set.

Example:

torify --user foo --pass password curl https://example.com/

Then, using a different set of credentials will get you a different circuit and exit relay:

torify --user foo2 --pass password2 curl https://example.com/

You can achieve the same using Tor's socks proxy directly with curl, and specify a unique proxy username/password combination to get stream isolation as well.

Example:

curl -Lv --socks5-hostname 127.0.0.1:9050 \
  --proxy-user foo:password \
  https://example.com/

Then, using a different set of credentials will get you a different circuit and exit relay:

curl -Lv --socks5-hostname 127.0.0.1:9050 \
  --proxy-user foo2:password2 \
  https://example.com/
