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.

RUN-MAILCAP(1) Run Mailcap Programs RUN-MAILCAP(1)NAME
run-mailcap, view, see, edit, compose, print - execute programs via entries in the mailcap file
SYNOPSIS
run-mailcap --action=ACTION [--option[=value]] [MIME-TYPE:[ENCODING:]]FILE [...]
The see, edit, compose and print versions are just aliases that default to the view, edit, compose, and print actions (respectively).
DESCRIPTION
run-mailcap (or any of its aliases) will use the given action to process each mime-type/file in turn. Each file is specified as its mime-
type, its encoding (e.g. compression), and filename together, separated by colons. If the mime-type is omitted, an attempt to determine
the type is made by trying to match the file's extension with those in the mime.types files. If no mime-type is found, a last attempt will
be done by running the file command, if available. If the encoding is omitted, it will also be determined from the file's extensions.
Currently supported encodings are gzip (.gz), bzip2 (.bz2), xz (.xz), and compress (.Z). A filename of "-" can be used to mean "standard
input", but then a mime-type must be specified.
Both the user's files (~/.mailcap; ~/.mime.types) and the system files (/etc/mailcap; /etc/mime.types) are searched in turn for informa-
tion.
EXAMPLES
see picture.jpg
print output.ps.gz
compose text/html:index.htm
extract-mail-attachment msg.txt | see image/tiff:gzip:-
OPTIONS
All options are in the form --<opt>=<value>.
--action=<action>
Performs the specified action on the files. Valid actions are view, cat (uses only "copiousoutput" rules and sends output to STD-
OUT) , compose, composetyped, edit and print. If no action is specified, the action will be determined by how the program was
called.
--debug
Turns on extra information to find out what is happening.
--nopager
Ignores any "copiousoutput" directive and sends output to STDOUT.
--norun
Displays the found command without actually executing it.
SECURITY
A temporary copy of the file is opened if the file name matches the Perl regular expresssion "[^[:alnum:],.:/@%^+=_-]", in order to protect
from the injection of shell commands, and to make sure that the name can always be displayed in the current locale. In addition, the file
is opened using its absolute path to prevent the injection of command-line arguments, for instance using file names starting with dashes.
