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 with‐
       out 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 fin‐
	      ish.

       -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
