[Linux] Bash pwd用法: 显示当前工作目录

Overview

The pwd command stands for “print working directory.” It is used in Bash and other Unix-like operating systems to display the current directory you are in within the terminal. This command is particularly useful for confirming your location in the filesystem.

Usage

The basic syntax of the pwd command is as follows:

pwd [options] [arguments]

Common Options

• -L: Use the logical current working directory. This option shows the path as it is set by the shell, which may include symbolic links.
• -P: Use the physical current working directory. This option resolves all symbolic links and shows the actual path.

Common Examples

Here are some practical examples of using the pwd command:

1. Basic Usage: Simply type pwd to display the current directory.

   pwd
   

2. Using the Logical Option: Display the logical path of the current directory.

   pwd -L
   

3. Using the Physical Option: Display the physical path of the current directory.

   pwd -P
   

4. In a Script: You can use pwd in a script to store the current directory in a variable.

   current_dir=$(pwd)
   echo "You are currently in: $current_dir"
   

Tips

• Use pwd frequently to keep track of your current location in the filesystem, especially when navigating through multiple directories.
• Combine pwd with other commands in scripts to create dynamic paths based on the current working directory.
• Remember that the output of pwd can be affected by the options you choose, so select -L or -P based on your needs.
