How to Display the Current Working Directory in Linux Using the pwd Command

Introduction

The pwd command is a Linux utility used to display the working directory to enable smooth navigation in your file system. It's also known as print working directory (pwd) and enables filesystem navigation, script, file, and directory management.

This article explains how to use the pwd command in Linux to manage your working directory environment.

pwd Command Syntax

Below is the basic pwd command syntax:

$ pwd [options]

Within the above command, pwd outputs the full working directory path with specific filtering options.

pwd Command Options

Understanding Logical and Physical Paths

• Logical Path (-L): Displays the working directory path as it appears in your terminal environment including any symbolic links.
• Physical Path (-P): Displays the working directory's physical location on the filesystem and resolves symbolic links to their real locations.

Practical Examples of the pwd Command

1. View the active working directory.

   console Copy

   $ pwd
   

   Explain Code

   The above command outputs your full working directory path.

   Output:

   

2. Display the logical working directory.

   console Copy

   $ pwd -L
   

   Explain Code

   The above command displays the logical working directory path including any symbolic links.

   Output:

   

3. Display the physical working directory path.

   console Copy

   $ pwd -P
   

   Explain Code

   The above command outputs the full working directory path and resolves any symbolic links to display the directory structure on the filesystem.

   Output:

   

Practical Scenarios for Using pwd

Capturing the current working directory (pwd) is essential in shell scripting to enable the creation of relative paths or set up of the script's working directory. Follow the steps below to use pwd in a script.

1. Create a new sample script file my_script.sh using a text editor such as Nano

   console Copy

   $ nano my_script.sh
   

   Explain Code

2. Add the following contents to the file.

   bash Copy

   #!/bin/bash
   current_dir=$(pwd)
   echo "The script is running in: $current_dir"
   

   Explain Code

3. Enable execute permissions on the script.

   console Copy

   $ sudo chmod +x my_script.sh
   

   Explain Code

4. Run the script

   console Copy

   $ bash my_script.sh
   

   Explain Code

   Output:

   

5. Run the following command to use pwd while switching directories and verify the active position in your file system.

   console Copy

   $ cd /home/user/documents && pwd
   

   Explain Code

   Output:

   /home/user/documents

   The above command switches to the /home/user/documents directory and prints the working directory to verify the active file system position.

Advanced Usage Scenarios

1. Combine pwd with cd to enable directory navigation.

   console Copy

   $ cd /tmp && pwd
   

   Explain Code

   The above command changes the working directory to /tmp and displays the active directory.

   Output:

   

2. Use pwd with ls.

   console Copy

   $ pwd && ls
   

   Explain Code

   The above command displays the working directory and lists all included contents.

   Output:

   

3. Store the working directory in a variable and view the result using echo.

   console Copy

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

   Explain Code

   Output:

   

4. Combine pwd with find to search search files.

   console Copy

   $ find $(pwd) -name "*.log"
   

   Explain Code

   The above command searches for all files with the .log extension in the active working directory.

   Output:

   

5. Use the pwd command in error handling.

   console Copy

   $  if [ ! -d "/some/directory" ]; then
        echo "Directory not found, current location is: $(pwd)"
      fi
   

   Explain Code

   The above command displays the working directory result to enable debugging in a scripts.

   Output:

   

6. Use pwd in automation scripts.

   • Create a new sample script file pwd_scrpt.sh using a text editor such as Nano

     console Copy

     $ nano pwd_script.sh
     

     Explain Code

   • Add the following contents to the file.

     bash Copy

     #!/bin/bash
     if [ $(pwd) != "/expected/directory" ]; then
         echo "Please navigate to /expected/directory before running this script."
         exit 1
     fi
     

     Explain Code

     Save and close the file.

   • Enable execute permissions on the file.

     console Copy

     $ chmod +x pwd_script.sh
     

     Explain Code

   • Run the script

     console Copy

     $ bash pwd_script.sh
     

     Explain Code

     The above bash script automates tasks that depend on the active working directory to run perform a specific function.

   Output:
