NAME

       varnishadm - Control a running Varnish instance

SYNOPSIS

       varnishadm [-n ident] [-t timeout] [-S secretfile] [-T [address]:port] [command [...]]

DESCRIPTION

       The  varnishadm  utility  establishes a CLI connection to varnishd either using -n name or
       using the -T and -S arguments. If -n name is given the location of the secret file and the
       address:port  is  looked up in shared memory. If neither is given varnishadm will look for
       an instance without a given name.

       If a command is given, the command and arguments are sent over the CLI connection and  the
       result returned on stdout.

       If  no command argument is given varnishadm will pass commands and replies between the CLI
       socket and stdin/stdout.

OPTIONS

       -n ident
              Connect to the instance of varnishd with this name.

       -S secretfile
              Specify the authentication secret file. This should be the same -S argument as  was
              given to varnishd. Only processes which can read the contents of this file, will be
              able to authenticate the CLI connection.

       -t timeout
              Wait no longer than this many seconds for an operation to finish.

       -T <address:port>
              Connect to the management interface at the specified address and port.

       The syntax and operation of the actual CLI interface is described  in  the  varnish-cli(7)
       manual page. Parameters are described in varnishd(1) manual page.

       Additionally,  a  summary  of  commands can be obtained by issuing the help command, and a
       summary of parameters can be obtained by issuing the param.show command.

EXIT STATUS

       If a command is given, the exit status of the varnishadm utility is zero  if  the  command
       succeeded, and non-zero otherwise.

EXAMPLES

       Some ways you can use varnishadm:

       varnishadm -T localhost:999 -S /var/db/secret vcl.use foo
       echo vcl.use foo | varnishadm -T localhost:999 -S /var/db/secret
       echo vcl.use foo | ssh vhost varnishadm -T localhost:999 -S /var/db/secret
