 SYNOPSIS

              file  [-m] [-f namesfile]  filename 

 SYNOPSIS

        file  [-L]  [-f filelist]  filename

 FUNCTION

       Determines the type of the file, i.e. ASCII,

       executable, object, nroff, text, etc.  If the

       file is an ASCII file, file examines the first

       512 bytes and tries to guess its language.

 OPTIONS

          -f - examines all of the files listed in filelist

          -L - if a file is a link, test the file referenced by the link

 OPTIONS

          -f - examines all of the files listed in namesfile

          -m - sets the access time for the examined file to the

               current time

 Let us assume that there is a file called

 counter, with the above text:

                 counter

       counter(n)   /* count 1 bits in n */

           unsigned n;

       {

           int b;

           for (b = 0; n != 0; n >>= 1)

               if ( n & 01)

                   b++;

           return(b);

       }

  Let us use the file command

  to determine the type of the file counter:

  Please type: file counter

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please type file counter

 Please type file counter

 I guess I must type this for you:

 $PROMPT$

 Observe the result on the terminal!

 file counter                          

 counter:        c program text
