mime-extension

Find the file extensions associated with mime-type on a Linux systems.

Note that the reverse query - going from extension to mime-type can be achieved using the xdg-mime command-line tool. You can go from the contents of a file to a mime-type using the file command with file -b --mime-type $FILE.

Motivation

There appears to be no standard script to perform this function but a solution and script is provided on stack exchange by Kamil Maciorowski. I needed this functionality, and where possible I prefer my solutions to work on any computer and be easily installed so I am packaging this as a script.

Additionally, the solution in stack overflow is based upon /etc/mime.types but I think most desktop environmenets now use the XML files /usr/share/mime combined with ~/.local/share/mime for this information.

Installation

You can install mime-extension using pipx:

pipx install mime-extension

Usage

mime-extension text/html

Note that there are often multiple file extensions.
