Displaying the Entire History: sccs get -m -p

If you want to see a listing of all changes made to the file and the delta in which each was made, you can use the -m and -p options to get:

$ sccs get -m -p program.c
1.2 
1.2 #define L_LEN 256 
1.1
1.1 #include <stdio.h>
1.1
.  .  .  
84

To find out what lines are associated with a particular delta, you can pipe the output through grep(1V):

$ sccs get -m -p program.c | grep '^1.2'

You can also use -p by itself to send the retrieved version to the standard output, rather than to the file.
