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
