The shell offers the Tab completion for the user's entered commands with names of files and directories relative to the current directory and with available commands. It also allows selecting a completion from the list if there is more than one completion available.

It is possible to set the amount of the completions displayed on the list in the shell's options.

Additionally, the shell offers the Tab completion for arguments of commands. By default, the completion offers only names of directories and files as the completion. Changing its setting is possible in two ways:

1. Manually

   By using command completion add to add a new completion or completion edit [id] to edit an existing one, where ID is an ID of the completion to edit. You will be asked for several things during setting, like the name of the command and type of its parameters. It is possible to limit parameters only to directories or even disable the completion completely. If you select custom type of the completion, you will be also asked for the accepted values for the completion.

2. Importing from a file

   It is possible to import a completion from a file, previously generated with the command completion export [id] [filename] where filename is the name of the file to which the completion will be exported and ID is an ID of the completion to export. To import that completion, use the command completion import [filename] where filename is the name of the file to import.

Command completion export [id] [filename] exports the selected completion as a configuration file. It contains fields:

• Command: the command for which the completion is.
• Type: the type of completion. Can be: Directories only, Files only, Directories and files, Commands, Custom or Completion for the selected command should be disabled.
• Values: the values available for the completion. It is needed only for Custom type of the completion. All values must be separated by semicolon and in quotes.

For example, the file with an exported completion can look that:

Command=ls
Type=Custom
Values="te;ew;wr"

Command completion allows managing the Tab completions for commands, like deleting them, previewing or listing all of them. For more information about the command and its subcommands, please look at the corresponding shell's help entries.
