Tree Utility

A simple command-line utility written in Go to display the directory structure in a tree-like format.

Features

• Display files and directories in a structured, easy-to-read tree format.
• Optionally display hidden files and directories using the -a flag.
• Exclude specific files or directories by name using the -exclude flag.

Installation

1. Install Go (if not already installed).
2. Clone this repository or copy the tree.go file.

   git clone https://github.com/vovakirdan/tree-view.git
   cd tree-view

3. Build the utility:

   go build tree.go

---

Install in PATH

If you want to use it from anywhere in your linux system!

0. Compile. Note that you can specify output file name.
1. Copy (or move) binary to dir that included in PATH. As usual, it is a /usr/local/bin

sudo cp tree /usr/local/bin/tree

---

For MacOS

You can use also:

sudo mv tree /usr/local/bin/

But sometimes somethings goes wrong and you have no such dir. Then, of course, you can create it:

sudo mkdir /usr/local/bin

An then, if you don't have this path in your $PATH go:

1. Open configuration file for your sh. For mac os it is zsh (~/.zshrc) by default, for bash it is bash profile (~/.bash_profile)

vim ~/.zshrc

2. Add export PATH=$PATH:/usr/local/bin to the file if don't even exists
3. Save and run source ~/.zshrc Then you can just move it to the dir.

Via Brew

1. Move binary file to the homebrew path:

mkdir -p /usr/local/Cellar/tree/1.0/bin
mv tree /usr/local/Cellar/tree/1.0/bin/

2. Create symbol link to utility:

ln -s /usr/local/Cellar/tree/1.0/bin/tree /usr/local/bin/tree

Finally:

Check access via tree --help. If everything is ok, you will see the help.

Usage

Run the utility from the command line:

./tree [options] <directory>

Options:

• -a
  Show hidden files and directories (those starting with a dot .).
• -exclude=<names>
  Exclude files and directories by name. Pass a comma-separated list.
• -emoji
  Shows emoji near the file or path.

Examples

1. Display the current directory:

   ./tree .

2. Show hidden files and directories:

   ./tree -a .

3. Exclude specific directories (e.g., node_modules and build):

   ./tree -exclude=node_modules,build .

4. Combine options: Show hidden files and exclude specific directories:

   ./tree -a -exclude=.git,node_modules .

Output Example

Given a directory structure:

GoCall/
├── go.mod
├── main.go
├── server/
│   └── main.go
├── static/
│   ├── app.js
│   └── index.html
└── .git/
    ├── HEAD
    └── config

Without hidden files:

./tree GoCall

Output:

GoCall/
├── go.mod
├── main.go
├── server/
│   └── main.go
└── static/
    ├── app.js
    └── index.html

With hidden files:

./tree -a GoCall

Output:

GoCall/
├── .git/
│   ├── HEAD
│   └── config
├── go.mod
├── main.go
├── server/
│   └── main.go
└── static/
    ├── app.js
    └── index.html

With emoji flag

./tree -emoji

Output

📂 gocall/
├── 📜 GoCall
├── 📂 client/
│   ├── 💻 main.go
│   └── 💻 webrtc.go
├── 📜 go.mod
├── 📜 go.sum
├── 💻 main.go
├── 📂 server/
│   ├── 💻 main.go
│   ├── 💻 signaling.go
│   └── 💻 webrtc.go
└── 📂 static/
    ├── 💻 app.js
    └── 📜 index.html

Notes

• Hidden files and directories (starting with .) are ignored by default.
• The program works recursively and handles any depth of directories.
