How to Get the Directory of a File in Terminal

Understanding the directory of a file is a fundamental skill for anyone working with computers, especially in the terminal. Whether you’re a beginner or a seasoned pro, knowing how to find the directory of a file can save you time and frustration. In this guide, I’ll walk you through various methods to retrieve the directory of a file in the terminal, using different operating systems and commands.

Using the `pwd` Command

The `pwd` command stands for “print working directory.” It’s one of the most straightforward ways to find out the current directory you’re in. Here’s how you can use it:

pwd

This command will display the full path of the directory you’re currently in. If you want to find the directory of a specific file, you can use the `pwd` command in combination with other commands.

Using the `find` Command

The `find` command is a powerful tool that can search for files and directories in a specified path. To find the directory of a file, you can use the following syntax:

find /path/to/search -name "filename"

This command will search for the file named “filename” in the specified path. If the file is found, the command will output the full path of the file, which includes the directory.

Here’s an example:

find /home/user/documents -name "report.txt"

This command will search for the file “report.txt” in the “/home/user/documents” directory and its subdirectories. If the file is found, it will display the full path, such as “/home/user/documents/report.txt”.

Using the `realpath` Command

The `realpath` command resolves all symbolic links, relative paths, and other path-related issues to provide the absolute path of a file. To find the directory of a file, you can use the following syntax:

realpath /path/to/file

This command will output the absolute path of the file, including the directory. For example:

realpath /home/user/documents/report.txt

This command will output “/home/user/documents/report.txt”, which is the absolute path of the file “report.txt” in the “/home/user/documents” directory.

Using the `dirname` Command

The `dirname` command is specifically designed to extract the directory name from a given file path. To find the directory of a file, you can use the following syntax:

dirname /path/to/file

This command will output the directory name of the file. For example:

dirname /home/user/documents/report.txt

This command will output “/home/user/documents”, which is the directory of the file “report.txt” in the “/home/user/documents” directory.

Using the `readlink` Command

The `readlink` command is similar to `realpath`, but it’s specifically designed to handle symbolic links. To find the directory of a file, you can use the following syntax:

readlink -f /path/to/file

This command will output the absolute path of the file, including the directory, even if the file is a symbolic link. For example:

readlink -f /home/user/documents/report.txt

This command will output “/home/user/documents/report.txt”, which is the absolute path of the file “report.txt” in the “/home/user/documents” directory, even if the file is a symbolic link.

Using the `locate` Command

The `locate` command is a fast file search utility that uses a previously built database to quickly locate files. To find the directory of a file, you can use the following syntax:
