Launch Broot

When the installation is complete, you may start broot with either

broot

or

br

If your shell is compatible, you should prefer br which enables some features like cd from broot.

You can pass as argument the path you want to see, for example

br ~

Navigate

Basics

When you start broot, the current directory is displayed, with some directories open and or some lines truncated, in order to fit the available height.

The first line is called the root, and is currently selected.

From here you may navigate using the following keys:

There are also a few more shortcuts:

Fuzzy Patterns

You would usually not just navigate this way: you'll filter the tree.

This is done simply by typing a few letters.

The pattern filters the tree while you type. It's interpreted in a fuzzy way so that you don't have to type all the letters or even consecutive letters. The best match is automatically selected.

For example:

search hel

Hitting esc clears the current pattern.

Regular Expressions

If there's a / before or after the patten, it's interpreted as a regular expression.

For example /pat+ern would match "patern.zip" or "some_patttern.rar" but not "pATTern".

If you want the regex to be case insensitive, add the i flag: pat+ern/i.

Flags

Flags are displayed at the bottom right, showing the settings regarding hidden files and .gitignore rules.

Toggles

Initially, broot doesn't show files whose name starts with a dot, or files declared as ignored by a .gitignore file. Permissions and file sizes aren't shown.

This behavior is tuned with several toggles.

name shortcut description
toggle_files files toggle showing files (or just folders)
toggle_git_ignore gi toggle use of .gitignore
toggle_hidden h toggle showing hidden files
toggle_perm perm toggle showing file permissions
toggle_sizes sizes toggle showing sizes
toggle_trim_root t toggle removing nodes at first level too (default)

To apply one, just type a space (or :), then the start of its shortcut, then hit .

For example typing :s then enter will show directory sizes:

dev sizes

You may notice a scrollbar on this screenshot. You may sometimes want to not trim the first level of the tree, which is done by using the toggle_trim_root (and which is also automatically done when displaying sizes).

gitignore

The gitignore "toggle" has 3 modes:

mode display filtering
no gi:n .gitignore files aren't applied
yes gi:y .gitignore rules are applied whenever they're found. If the root contains several git projects, it means different visible subtrees follow different sets of rules
auto gi:a if the current root is a git directory or inside one, then the rules are applied. Otherwise they aren't

Quitting broot

Other than executing a command leaving broot, there are several ways to quit:

Verbs & Command

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 means taking the selected directory and 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}"

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

rm

As for filters, hitting esc clears the command.

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}

Verbs using 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}"

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:

md

In this screenshot, we 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.

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).

Most common Commands

Note

Remember that you may select a verb by just typing the first letters of its name or shorcut

Command Shortcut Usage
back revert to the previous state (mapped to esc)
cd leave broot and change directory (mapped to alt-enter)
focus goto display the selected directory (mapped to enter)
help ? go to the help screen
open open file according to OS settings (mapped to enter )
parent p move to the parent directory
print_path pp print path and leaves broot
quit q quit the application

File Manipulation

Command Shortcut Usage
mkdir md create a new directory, using a name you provide as argument
mv move a file or directory, to a relative path you provide as argument
rm remove the selected file or directory

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.

Launch Arguments

broot and br can be passed as argument the path to display.

They also accept a few other arguments which you can view with br --help.

Most of them are display toggles, which may be useful when aliasing the function but which are accessible from inside the application anyway.

Some of them are a little special, though, and are explained below:

the --outcmd launch argument

Some external commands can't be executed from a program.

This is especially the case of cd, which isn't a program but a shell function. In order to have any useful effect, it must be called from the parent shell, the one from which broot was launched, and a shell which isn't accessible from broot.

The trick to enable broot to cd your shell when you do alt-enter is the following one:

Most users have no reason to use --outcmd on their own, but it can still be used to write an alternative to br or to port it to shells which aren't currently supported.

the --out launch argument

If you provide a path to broot with --out, then a few commands won't execute anything directly but will instead write the relevant path as a line in the given file.

This may be used by shell functions or other programs calling broot, in a similar way to --outcmd, for example in conjonction with ̀ --cmd`.

the --cmd launch argument

This argument lets you pass commands to broot. Those commands are executed exactly like any command you would type yourself in the application, a space meaning broot must wait for the end of execution.

For example if you launch

br --cmd cow /

Then broot is launched in the / directory and there's simply a filter typed for you.

If you do

br --cmd "/^vache :p"

Then broot looks for a file whose name starts with "vache" and focus its parent.

If you do

br --cmd "mucca$/ :cd"

then broot searches for a file whose name ends with "mucca", and cd to the closest directory, leaving you on the shell, in your new directory (you may not have the time to notice the broot guy was displayed).

The --cmd argument may be the basis for many of your own shell functions or programs.

Note

Due to the way a new char cancels an in progress search, you can't pass both a search and a verb in the same command, you have to separate them with a space. That is, if you want to search for thing then do :rm on the best match (assuming you like to live dangerously), you have to do br --cmd "thing :rm" instead of br --cmd "thing:rm".
