file

Determine file type. More information: https://manned.org/file.

• Give a description of the type of the specified file. Works fine for files with no file extension:

file {{path/to/file}}

• Look inside a zipped file and determine the file type(s) inside:

file {{[-z|--uncompress]}} {{foo.zip}}

• Allow file to work with special or device files:

file {{[-s|--special-files]}} {{path/to/file}}

• Don't stop at first file type match; keep going until the end of the file:

file {{[-k|--keep-going]}} {{path/to/file}}

• Determine the MIME encoding type of a file:

file {{[-i|--mime]}} {{path/to/file}}
