NAME

       varnishadm - Control a running Varnish instance

SYNOPSIS

       varnishadm  [-h]  [-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

       -h     Print program usage and exit.

       -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:

          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
