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.
