"whereis squid" should give you the path to your squid binary if it is installed in a sensible place.Sorry for such an inane post, but can someone tell me what command to run that will show the version of Squid is installed on a red hat server?
Once you found the binary you can do a /path_to_squid/squid -vChances are that the path is /usr/sbin, but I am not sure as I always use self compiled squid's.
