There's the `file` command; try `man file`.  Quick summary:  
$ file foo
displays something like
foo: PostScript document text

There are a few options you can use.  If you use -i then it will return a 
machine-readable MIME type rather than a human-readable explanation; if you 
use -b then it will omit the filename from the output.

$ file -bi foo
displays something like
application/postscript

Note that the default behaviour is to treat symbolic links as a file type in 
their own right; but if you use -L, then it will follow a symlink and report 
the type of the actual file.

You might use something like
MIMETYPE=`file -Lbi $FILENAME`
in a shell script, to get the MIME type of a file.
