 SYNOPSIS

          file  [-m mfile] [-f namesfile] 

 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 the files listed in the namesfile

       -m    -    Sets the access time of the examined file

                  to the current time

 Let us assume that there is a file called

 counter, with the following 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);

       }

Command for determining file type, practice, - 1.8.2.0.1

 Let us use the file command

 to determine the type of the file counter:

 Please enter the appropriate command.

 $PROMPT$

 That is correct!

 You've got it on the 2nd try.

 Good, you understand the concept.

 Please use the file command on the file counter

 Please type file counter

 I guess I must type this for you:

 PA: 2

 $PROMPT$

 Observe the result on the terminal!
