sometimes it is necessary to do some actions with squid (eproxy) on eSafe on the command-line. For instance, you want a quick stop-and-start of squid or do some debugging. The following options can be used in the CLI environment;

Usage: squid [-hvzCDFNRYX] [-d level] [-s | -l facility] [-f config-file] [-u port] [-k signal]
       -d level  Write debugging to stderr also.
       -f file   Use given config-file instead of
                 /opt/eproxy/etc/squid.conf
       -h        Print help message.
       -k reconfigure|rotate|shutdown|interrupt|kill|debug|check|parse
                 Parse configuration file, then send signal to
                 running copy (except -k parse) and exit.
       -s | -l facility
                 Enable logging to syslog.
       -u port   Specify ICP port number (default: 3130), disable with 0.
       -v        Print version.
       -z        Create swap directories
       -C        Do not catch fatal signals.
       -D        Disable initial DNS tests.
       -F        Don’t serve any requests until store is rebuilt.
       -N        No daemon mode.
       -R        Do not set REUSEADDR on port.
       -S        Double-check swap during rebuild.
       -X        Force full debugging.
       -Y        Only return UDP_HIT or UDP_MISS_NOFETCH during fast reload.

For instance, when you want to stop-and-start squid (to flush DNS cache), you can use the following;

# /opt/eproxy/sbin/squid –k shutdown
# /opt/eproxy/sbin/squid
