dirname

The dirname command line tool is used to extract the directory path from a given file or directory path. It removes the last component of the path and returns the remaining parent directory path.

Here's an example usage:

$ dirname /path/to/file.txt
/path/to

In this example, the dirname command extracts the directory part from the file path /path/to/file.txt, leaving the path /path/to.

The dirname command can be useful when writing scripts or performing certain operations on file or directory paths, as it allows you to extract and manipulate the directory portion separately from the filename or last component of the path.
