file

The default option that requires no installation would be to use the file command. For our code example we will work with files from the General Example Files.

Usage

file --mime-type <name of the file>

Input

file --mime-type 6285633006_R03C01_Red.idat

Expected Output

6285633006_R03C01_Red.idat: application/octet-stream

Adding the -b flag returns only the MIME type for the selected file without the filename.

Input

file --mime-type -b 9969477031_R02C01_Red.idat

Expected Output

application/octet-stream
