I have a directory of 3000 files without extensions (Solaris 5.10).
I would like to iterate the file names through the 'file' command and output their mime types (most are pdf or jpg, but a very few might be psd or swf which show simply as 'data')
So, I would like the output of the 'ls' command to become the input of the
'file -f' command, but cannot get them to work together with redirection or piping. I'll probably need a script of some sort.
I can output the results of the ls command to a file, but then I need to have the file command read the contents (line by line) of the file.
Ideally, the script would also rename the file with the proper extension (.pdf, .jpg, .gif, .htm) if it recognizes it.
