1.1       root        1: #print
                      2: You have already had some practice in using ">" to capture
                      3: the output of a program.  In much the same way, it
                      4: is possible to arrange for a program to take its input not
                      5: from the terminal but from a file.
                      6: Most UNIX programs are written so that they will read either
                      7: the terminal or from a list of filenames.
                      8: To have a program read from a file instead of the terminal,
                      9: use the "<", like this:
                     10:   pr <file
                     11: As a simple experiment, determine if
                     12:   pr <file
                     13: is absolutely identical to
                     14:   pr file
                     15: Answer yes or no.
                     16: #create junk
                     17: you can use this file to play with.
                     18: #copyin
                     19: #user
                     20: #uncopyin
                     21: #match no
                     22: #log
                     23: #next
                     24: 4.1b 10
                     25: 4.2a 5
