After a command has copied the new delta to the s-file, it displays a message showing
the new SID and the number of lines inserted, deleted, or left unchanged in the new
version. For example, if the C program has been changed to
#include
main ()
{
inti = 2;
printf("This is version 1. %d \n ", i);
}
the command displays the message
1.2
3 inserted
1 deleted
5 unchanged
Once a new version is saved, the next get command retrieves the new version. The
command ignores previous versions. If you wish to retrieve a previous version, you must
use the -r option of the get command as described in the next section.
Retrieving a Specific Version
You can retrieve any version you wish from an s-file by using the -r (for "retrieve")
option of the get command. The command has the form
get [ -e ] -rSID s. filename • • •
where -e is the edit option, -rSID gives the SID of the version to be retrieved, and
s.filename is the name of the s-file containing the file to be retrieved. You may give
more than one file name. Names must be separated with spaces or tabs.
The command retrieves the given version and copies it to the file having the same name
as s-file but with the s. removed. The file has read-only permission unless you also give
the -e option. If multiple file names are given, one text file of the given version is
retrieved from each. For example, the command
get -r1 .1 s.demo.c
retrieves version 1.1 from the s-file s.demo.c, but the command
get -e -r1.1 s.demo.c s.def.h
retrieves for editing a version 1.1 from both s.demo.c and s.def.h. If you give the
number of a version that does not exist, the command displays an error message.
