Yes the quit was a typo it should probably be something like exit 2, still it's good to know that your trap code is not executing. The exit is nice as it allows anything that calls this script to know if an interupt was trapped or not.


Things to note is that polipo is a background daemon (I assumed this because it's being started by an rc.d script). tor on the otherhand is running in the foreground control dosn't return to your script until tor exits (as you said usually as a result of the users typing ctrl-c).

So you can see that traping interupts after tor exists is closing the barn door after the horse has bolted.

I moved the trap to before tor starts and also added a clean shutdown after tor, this is for instances where tor exist with a ctrl-c interupt (e.g. tor fails to start due to error, crashes, or some user input causes tor to exit without the need for ctrl-c).

TOR-RESOLVE(1)                                                      Tor Manual                                                      TOR-RESOLVE(1)

NAME

       tor-resolve - resolve a hostname to an IP address via tor

SYNOPSIS

       tor-resolve [-4|-5] [-v] [-x] hostname [sockshost[:socksport]]

DESCRIPTION

       tor-resolve is a simple script to connect to a SOCKS proxy that knows about the SOCKS RESOLVE command, hand it a hostname, and return an IP
       address.

       By default, tor-resolve uses the Tor server running on 127.0.0.1 on SOCKS port 9050. If this isn't what you want, you should specify an
       explicit sockshost and/or socksport on the command line.

OPTIONS

       -v
           Display verbose output.

       -x
           Perform a reverse lookup: get the PTR record for an IPv4 address.

       -5
           Use the SOCKS5 protocol. (Default)

       -4
           Use the SOCKS4a protocol rather than the default SOCKS5 protocol. Doesn't support reverse DNS.

SEE ALSO

       tor(1), torify(1).

       See doc/socks-extensions.txt in the Tor package for protocol details.
