VARNISHADM(1)

NAME
varnishadm - Control a running varnish instance

SYNOPSIS
varnishadm [-t timeout] [-S secret_file] -T address:port [command [...]]

DESCRIPTION
The varnishadm utility establishes a CLI connection using the -T and -S arguments.

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.

The following options are available:

-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.

Available commands and parameters are documented in the 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
