MIME type of many files

To obtain MIME type for multiple files, we can script the utility commands in a for loop. As an example, here is one possible script using the xdg-mime command to obtain the MIME type for each file and store the results as a tab-separated-values file.

for file in {.,}*; do      # For all files in the current directory with all the Kids First data files
  mime_type=`xdg-mime query filetype $file`        # Obtain MIME type
  echo "$file   $mime_type" >> example_mime_types.tsv   # Write to output file
done

Siegfried has a built-in option to obtain the file format information for files in a directory.

Usage

 sf <path to the directory>

Input

# Example code combined with other flags
sf -sig custom.sig -csv example_files_MIME/ > example_files_MIME.csv

# View the results in table format on command line
cat example_files_MIME.csv | column -t -s, | less -S
