VARNISHADM(1) VARNISHADM(1)
NAME
varnishadm - Control a running varnish instance
SYNOPSIS
varnishadm [-t timeout] [-S secret_file] [-T address:port] [-n name] [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
-t timeout
Wait no longer than this many seconds for an operation to finish.
-S secret_file
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 address:port
Connect to the management interface at the specified address and port.
-n name
Connect to the instance of varnishd with this name.
The syntax and operation of the actual CLI interface is described in the varnish-cli(7) manual page. Parameteres are described in var-
nishd(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.
