Often you may want to extract a filename from a path in Bash.
The easiest way to do so is by using the basename command, which is designed to perform this exact task.
Here is how to use this command in practice:
my_file="$(basename "${my_path}")"
This particular example extracts the filename from the path specified by the $my_path variable and saves the results in a new variable named $my_file.
The following example shows how to use this syntax in practice.
Example: How to Extract Filename from Path in Bash
Suppose that we have a file named teams.txt with the following file path:
- c:/users/bobbi/teams.txt
Suppose that we would like to extract only the filename, which would be the following:
- teams.txt
We can use the following syntax to do so:
my_path='/c/users/bobbi/teams.txt'
my_file="$(basename "${my_path}")"
echo $my_file
The following screenshot shows how to use this syntax in practice:
Notice that when we use the echo statement to view the contents of the $my_file variable we can see that it contains only the filename for the path that we specified.
Bonus: To instead extract only the directory from the path, you can replace basename with dirname.
