gls

made-with-Go GitHub go.mod Go version of a Go module Linux macOS Windows

It’s ls + du + tree with interactive TUI on your terminal! gls is created to easily view, filter and search your files, folders and directories with their size whenever you need to open up some storage space. It wouldn’t be wrong to say that gls is a minimal yet powerful file manager CLI tool.

Installation

From Go package

Simply run:

go install go.sazak.io/gls/cmd/gls@latest

From Source Code

Installing gls on your machine with the source code is pretty simple: just clone the repo and install cmd/gls/main.go:

$ git clone https://github.com/ozansz/gls
$ cd gls
$ go install ./cmd/gls/main.go

After you run go install command, an executable file name gls is created in $GOPATH/bin. Now, you can simply run gls in terminal:

$ gls

For Ubuntu/Debian and derivatives

If you use a Debian-based distro on Linux, you can download the package which seems like gls_<VERSION_NUMBER>_amd64.deb from Releases page. Then, you can install it

For Windows

You can apply the similar procedure in PowerShell shown in the From Source Code section:

> git clone https://github.com/ozansz/gls
> cd .\gls\
> go install -v .\cmd\gls\main.go

Now, you can use gls in all directories.

Usage

There are two running modes of gls: TUI and text-based.

The TUI mode is interactive and you will be able to use all of the features of gls, such as searching by text/regular expression, traversing on the file tree, creating/opening/deleting files and many other things, until you close the program.

The text mode however, is fairly simple and is a literal combination of running tree and du altogether, with some additional features.

Default usage (TUI)

The command below runs gls with TUI, which is the default mode. It parses the file tree under the specified path along with the file and folder sizes on disk, then shows the tree view of the parsed tree.

gls -path ~/Downloads

Text mode

The command below does the same parsing process as the command above does. Except, this one just dumps the parsed tree as a the tree command does with the file/folder sizes and permissions, to the terminal.

gls -nogui -path ~/Documents

Features

gls includes (and still continues to include more) several features that mimic a normal file manager:

TUI shortcuts

Shortcut Command Description
q, ESC, ˆC quit Exits the program
c collapse Collapses all nodes in the file tree view
e expand Expands all nodes in the file tree view
s search Opens modal to search nodes (files and folders) by name
r regex search Same as search, but you can search using regular expressions
x restore Loads the original file tree view, mostly used after search and regex search
o open Opens the selected (on hover) file/folder with the default program
p open Opens modal to specify the executable path which will be used to open the selected (on hover) file/folder
BACKSPACE , DEL remove Removes the selected (on hover) file. Folder removal is currently not supported
m mark Marks/unmarks the selected (on hover) file or folder. Marked nodes can be used later for duplicate and move
u unmark Unmarks all the marked files and folders
n new Create a new file
d duplicate Copy/pastes the marked files and folders to a specified destination. The destination is specified by the text input of the opened form.
v open file in vim Opens file in VIM editor.
TAB, SPACE, ENTER toggle expand node Expands the node if currently collapsed, and vice versa, the selected (on hover) file or folder
ARROW KEYS, SCROLL navigate Navigates between nodes in the file tree view

Configuration

You can freely change the key bindings and shortcuts or configure the program for your needs from gui/core.go .

After your changes, run

go build cmd/gls/main.go

in the project directory.

In addition, if you think that your configurations or other changes seem necessary to improve the project, your contributions will be welcomed :)

Customize color palette

You can customize the color palette with .glsrc file. The only thing you need to do is create a .glsrc file in $HOME directory and set the colors as key-value pairs. An example is below:

GridTitleColor=blue
TreeViewTitleColor=yellow
FileInfoTitleColor=lightgreen
DirectoryColor=red
BorderColor=white
FileInfoAttrColor=orange
FileInfoValueColor=pink
SearchFormTitleColor=brown
UnmarkedFileColor=deeppink
MarkedFileColor=gray
FileInfoTabAttrWidth=30

When you run the program, the color palette values are overridden with values in .glsrc file. The file must be stored in $HOME directory and the file name must be .glsrc. Otherwise, the program uses the default color palette values.

Command line arguments

-debug
        Increase log verbosity
-fmt string
        size formatter, one of bytes, pow10 or none (default "bytes")
-ignore string
        Comma-separated ignore files that specify which files folders to exclude
-nogui
        text-only mode
-path string
        path to run on (required)
-sort
        sort nodes by size (default true)
-thresh string
        size filter threshold, e.g. 10M, 100K, etc.

You can also read this section from terminal by using gls without parameters.
