When working in a Bash environment, knowing how to find the current folder name can be incredibly useful. Whether you’re navigating through directories, managing files, or using version control with Git, having quick access to your working directory’s name helps streamline your workflow.

In this tutorial, we will explore different methods to find the current folder name using Bash commands. You’ll learn practical techniques that can enhance your command-line skills and improve your productivity. So, let’s dive into the various ways to discover the current folder name in Bash.

Using the pwd Command

One of the simplest and most straightforward ways to find the current folder name in Bash is by using the pwd command. This command stands for “print working directory,” and it displays the full path of the current directory you’re in. To extract just the folder name from this path, you can combine pwd with other commands.

Here’s how you can do it:

current_folder=$(basename "$(pwd)")
echo $current_folder

Output:

example_folder

In this example, pwd retrieves the full path of the current directory. The basename command then takes that path and strips away everything except for the final folder name. By assigning the result to the variable current_folder, you can easily echo it out or use it in your scripts. This method is efficient and works seamlessly in any Bash environment.

Using the Command Substitution

Another effective way to find the current folder name is by utilizing command substitution in Bash. This technique allows you to capture the output of a command and use it as an input for another command. Here’s how you can achieve this:

echo $(basename "$PWD")

Output:

example_folder

In this command, "$PWD" is an environment variable that always contains the path of the current working directory. By wrapping it with basename, you can directly print the current folder name to the terminal. This method is particularly useful for quick checks without needing to assign values to variables. It’s a quick and efficient way to get the job done.

Using the git rev-parse Command

If you’re working within a Git repository, you might want to find the current folder name in the context of your Git project. The git rev-parse command can be particularly useful here. It provides various information about the repository, including the current branch and, in this case, the current folder name.

Here’s how you can do it:

current_folder=$(basename "$(git rev-parse --show-toplevel)")
echo $current_folder

Output:

example_repo

In this example, git rev-parse --show-toplevel returns the absolute path to the root of the Git repository. By applying basename, you can extract just the repository’s folder name. This is particularly handy when you’re working in nested directories within a Git project and need to keep track of your current folder’s context.

Using the git status Command

Another Git-specific method to find the current folder name is by using the git status command. While this command is typically used to check the status of your repository, it can also provide the current directory context. Here’s how you can implement it:

current_folder=$(git status | head -n 1 | awk '{print $3}')
echo $current_folder

Output:

example_folder

In this command, git status provides a summary of the current state of your Git repository. The head -n 1 command extracts the first line of this output, which typically contains the current folder name. The awk command is then used to print the third word from that line, which should be the folder name. This method is slightly more complex but can be very useful in certain situations where you want to gather additional information from your Git status.

Conclusion

Finding the current folder name in Bash is a fundamental skill that can greatly enhance your command-line efficiency. Whether you choose to use simple commands like pwd and basename or delve into Git-specific commands like git rev-parse, each method has its own advantages. By incorporating these techniques into your workflow, you can navigate your file system and manage your projects more effectively. Now that you have a variety of methods at your disposal, you can choose the one that best fits your needs.
