fd — fast find

💬 "fd command"

fd is a fast and concise file search tool that replaces find. The command structure is simple and it excludes hidden files by default, resulting in clean output.

Instead of find's complex -name/-type options, it searches with a single intuitive pattern.

• Concept: Quickly finds files and directories that match the pattern.
• find replacement: Performs the same task with much shorter commands.
• Hidden files excluded: Excludes hidden files like .git by default.
• Regex support: Regex search is also possible with the -e option.

Installation and Download

fd can be installed via package managers or cargo.

To verify the installation, use fd --version or fdfind --version. On Debian/Ubuntu, it is fdfind.

Commonly Used Options

3 Essential Command Combinations

• fd -e conf — Quickly search for conf files only
• fd -e py -t f /var/www — Find Python files only
• fd -H -e log — Search for log files including hidden ones

💬 "Show me an example of quickly finding configuration files on a live server"

We've outlined a common scenario encountered on live servers in a step-by-step manner.

Step 1: Verify Installation

Check if it is installed.

fdfind --version || fd --version || sudo apt install -y fd-find

Step 2: Search for conf Files

Find conf files in the web root.

fd -e conf /var/www/html

Step 3: Files with a Specific Name

Find nginx-related files across the entire system.

fd -H nginx /etc

Live Execution Example

This shows the result of searching for conf files in the web root with fd. A clean list is displayed immediately.

In Practice, It's Used Like This

1. Finding Files in a Specific Project

Scenario — Find the entry point of an old project.

fd -e py -t f main

Result — A list of main.py files is displayed immediately.

Key point — Using -t f to distinguish files from directories makes the results clean.

2. Collecting Log Files

Scenario — Collect logs scattered across multiple directories at once.

fd -e log /var/log | head -10

Result — A list of log file paths is displayed.

Key point — It's much shorter and easier to read than find.

Live Execution Example

This shows the result of searching for nginx-related files across the entire system.

!fd command execution result 2

Live server in operation

Things to Note

• On Debian/Ubuntu, the command name is fdfind.
• Hidden files are excluded by default. To include them, use -H.
• If you need to execute directly instead of find's -exec, use it with xargs.
• If you provide an absolute path pattern, it will only search under that path.
