When you used a toggle, you executed a command in it simplest form: without argument and independant from the current selection.

The simplest verbs are just executed by typing a space (or :), then its first letters, then enter.

A verb can be related to the current selection. For example typing :p will execute the :parent verb, which focuses the parent of the selection (focusing a directory means making it the current root).

Verbs using the selection

The rm verb executes the standard rm command.

It's defined by this couple (invocation, execution):

invocation = "rm"
execution = "/bin/rm -rf {file}"

Selection based arguments:

name expanded to
{file} the complete path of the current selection
{parent} the complete path of the current selection's parent
{directory} the closest directory, either {file} or {parent}
{other-panel-file} the complete path of the current selection in the other panel
{other-panel-parent} the complete path of the current selection's parent in the other panel
{other-panel-directory} the closest directory, either {file} or {parent} in the other panel

Several selection based arguments can be used. For example the (built-in) :copy_to_panel verb is defined as

invocation = "copy_to_panel"
execution = "/bin/cp -r {file} {other-panel-directory}"

When you type a verb, the execution pattern is completed using the selection(s), the exact command is displayed in the status line:

rm

As for filters, hitting esc clears the command.

Verbs using user provided arguments

Some commands not only use the selection but also takes one or several argument(s).

For example mkdir is defined as

invocation = "mkdir {subpath}"
execution = "/bin/mkdir -p {directory}/{subpath}"

(it's now a built-in, you won't see it in the config file)

which means that if you type c/d, and the file /a/b/some_file.rs is selected, then the created directory would be a/b/c/d.

Example:

Before you type a subpath, broot tells you, in red, the argument is missing:

md

If you type an argument, the command to execute is computed and shown:

md

In this screenshot, you didn't type mkdir or its start but md. That's because the complete definition of this verb includes this line:

shortcut = "md"

Note

The help screen lists the whole set of available verbs, including the ones coming from the configuration.

Tab completion

When you type a verb, a few letters are often enough because broot just want enough of them to be sure there's no confusion. But sometimes there are a lot of verbs with the same start (especially if you add them liberally in the config file). You might want to have broot complete or propose the few possible completions. The tab key can be used for this purpose.

Tab completion is probably more useful even with paths you provide to verbs. It works intuitively.

Note: there's another solution to gain time when typing a path, especially when you're not sure of it: hitting ctrlp will open a new panel in which you can navigate until you have your selection that you validate with another hit on ctrlp (see panels).

Builtins & external commands, leaving or not

There are two types of verbs, differing by their execution pattern (which will be covered in more details in the configuration page):

A command may leave broot (for example to start a program), or not (the tree will be refreshed).

Adding verbs

You may start with the common set of verbs but you'll very quickly want to define how to edit or create files, and probably have a few personal commands.

That's why should see how to configure verbs.
