A more colorful, user-friendly implementation of ls written in Go.

You want to be able to glean a lot of information as quickly as possible from ls. Colors can help your mind parse the information. You can configure ls to color the output a little bit. Configuring ls is a hassle though, and the colors are limited.

Instead, you can use ls-go. It is highly colored by default. It has much fewer flags so you can get the behavior you want more easily. The colors are beautiful and semantic. A terminal with xterm-256 colors is required.

Features

• Works on Linux, Mac OS X, Windows, FreeBSD and most popular Unix-like systems.
• Outputs beautiful, semantic colors by default.
• Show paths to symlinks, and explicitly show broken links.
• Recurse down sub-directories.
• Emojis (if you're into that) and Nerd Fonts.
• Supports producing structured JSON and CSV output (to use with jq or similar tools).
• Full flexibility in choosing which columns / information to show.
• Support correct handling of CJK and other wide or invisible Unicode characters in tabular format.
• Better default sorting (by basename then extension) and 8 custom sorting methods (more than ls, although lacking a few of ls sorting methods).
• Support several formats for time and file sizes, along with custom Unix's time format and Go's time format.
• High compatibility with ls command's flags.

Screenshots

Nerd Font Support

ls-go works with Nerd Fonts. Simply add --nerd-font or -n to get file-specific icons. This won't work unless you have a Nerd Font installed and selected in your terminal emulator.

Install

Run go install github.com/ilius/ls-go@latest. Or clone the repository and run go install within ls-go directory.

Prior Art

This is inspired by athityakumar/colorls and monsterkodi/color-ls, ported to Go, with various modifications.

Known Issues

It fails on directories without executable permissions. The standard /bin/ls will also fail when reading non-executable directories, but only with certain options, like ls -l, ls --color=always (or ls -G on MacOS). This is because file metadata is needed to determine things like colors, and directories need to be executable to obtain the metadata of the contents. For example:

# create dir without -x permission
$ mkdir -m 644 test

# add a file
$ sudo touch test/foo

# plain `ls` still works
$ /bin/ls test
foo

# but `ls -l` fails
$ /bin/ls -l test

# and so does ls-go
$ ls-go test

Contributing

Contributions are muchly appreciated! Want to add a glyph for another file type? Did I forget an edge case? Is there another option that would be useful? Submit a PR! You might want to submit an issue first to make sure it's something I'd want to add though.

  • Go format: 2006-01-02 15:04

  • Show relative to current time, for example "1 day, 21:24:23 ago"

• + sign followed by a Unix time format (see man date or this link)
