Unambiguous partial keyword matching always occurs. The action +functions consume input until satisfied or until they fail. This model makes +for easy coding, but does not guarantee useful "help" output. It's up to the +CLI command writer to add useful help strings. + +You can find the source code of CLI commands by searching for instances of the +@c VLIB_CLI_COMMAND macro in the code source files. + +Please help maintain and improve this document to make and keep these commands +clear and useful! + +@todo Document where to modify this CLI intro text. + + +## Debug and Telnet CLI + +The debug CLI is enabled with the unix interactive parameter or startup +configuration option. This causes VPP to start without daemonizing and +presents a command line interface on the terminal where it is run. + +The Telnet CLI is enabled with the `cli-listen localhost:5002` option which +will cause VPP to listen for TCP connections on the localhost address port +@c 5002. A Telnet client can then connect to this port (for example, `telnet +localhost 5002`) and will receive a command line prompt. + +This configuration will enable both mechanisms: + +``` +unix { + interactive + cli-listen localhost:5002 +} +``` + +The debug CLI can operate in line mode, which may be useful when running +inside an IDE like Emacs. This is enabled with the option +`unix cli-line-mode`. Several other options exist that alter how this +CLI works, see the @ref syscfg section for details. + +The CLI starts with a banner graphic (which can be disabled) and a prompt. The +prompt will typically read `vpp` for a release version of VPP and `DBGvpp#` +for a development version with debugging enabled, for example: + + _______ _ _ _____ ___ + __/ __/ _ \ (_)__ | | / / _ \/ _ \ + _/ _// // / / / _ \ | |/ / ___/ ___/ + /_/ /____(_)_/\___/ |___/_/ /_/ + + vpp# + +versus: + + _______ _ _ _____ ___ + __/ __/ _ \ (_)__ | | / / _ \/ _ \ + _/ _// // / / / _ \ | |/ / ___/ ___/ + /_/ /____(_)_/\___/ |___/_/ /_/ + + DBGvpp# + +This prompt can be configured with the `unix cli-prompt` setting and the +banner is disabled with `unix cli-no-banner`. + +## CLI features + +The CLI has several editing features that make it easy to use. + +- Cursor keys left/right will move the cursor within a command line; + typing will insert at the cursor; erase will erase at the cursor. + +- Ctrl-left/right will search for the start of the next word to + the left or right. +- Home/end will jump the cursor to the start and end of the line. +- Cursor keys up/down and ^P/^N iterate through the command history + buffer. Lines from the history buffer may be edited. New commands + are added to the end of the buffer when executed; though + duplicates of the previous command are not added. +- ^U erases the line contents from the left of the cursor to the + start. +- ^K erases the contents from the cursor to the end. +- ^S/^R will search the command history forwards or in reverse for + a command; start typing for matches to auto complete. +- ^L will clear the screen (if supported by the terminal) and repaint + the prompt and any current line. The cursor position is also + retained. +- The CLI can be closed with the quit command. Alternatively, ^D on + an empty input line will also close the session. Closing the debug + session will also shutdown VPP. + +Output that exceeds the length of a terminal page will be buffered, up to a +limit. + +- Space or page-down displays the next page. +- Enter or down-arrow displays the next line. +- Page-up goes back a page. +- Up-arrow goes up a line. +- Home/end jump to the start/end of the buffered output. +- The key q quits the pager.

This section describes commonly-used +options and parameters. + +You can find command-line argument parsers in the source code by searching for +instances of the `VLIB_CONFIG_FUNCTION` macro. The invocation +`VLIB_CONFIG_FUNCTION(foo_config, "foo")` will cause the function +`foo_config` to receive all the options and values supplied in a parameter +block named "`foo`", for example: `foo { arg1 arg2 arg3 ... }`. + +@todo Tell the nice people where this document lives so that the might +help improve it! + +## Command-line arguments + +Parameters are grouped by a section name. When providing more than one +parameter to a section all parameters for that section must be wrapped in +curly braces. + +``` +/usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 } +``` + +Which will produce output similar to this: + + <startup diagnostic messages> + _______ _ _ _____ ___ + __/ __/ _ \ (_)__ | | / / _ \/ _ \ + _/ _// // / / / _ \ | |/ / ___/ ___/ + /_/ /____(_)_/\___/ |___/_/ /_/ + + vpp# <start-typing> + +When providing only one such parameter the braces are optional. For example, +the following command argument, `unix interactive` does not have braces: + +``` +/usr/bin/vpp unix interactive +``` + +The command line can be presented as a single string or as several; anything +given on the command line is concatenated with spaces into a single string +before parsing. + +VPP applications must be able to locate their own executable images. The +simplest way to ensure this will work is to invoke a VPP application by giving +its absolute path; for example: `/usr/bin/vpp <options>`. At startup, VPP +applications parse through their own ELF-sections (primarily) to make lists +of init, configuration, and exit handlers. + +When developing with VPP, in _gdb_ it's often sufficient to start an application +like this at the `(gdb)` prompt: + +``` +run unix interactive +``` + +## Configuration file + +It is also possible to supply parameters in a startup configuration file the +path of which is provided to the VPP application on its command line. + +The format of the configuration file is a simple text file with the same +content as the command line but with the benefit of being able to use newlines +to make the content easier to read.
