A command to list all file formats in a directory?

[rado84]

Hi. Is there a command that will list all file formats found in a directory with a recursive method (meaning that it will list all file formats in subdirs as well)?

You could use the file command to show filetype - is that what you're looking for?

$ file movies.txt
movies.txt: ASCII text

Then, push it through the files in your directory with something like the find command..
find . -type f | file -f -

No. But after an hour of searching, I think I found the command. It doesn't have the "-r" flag but it still displays the file extensions from all the subdirs and I'm gonna make an alias of it.

find . -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u
