A.2.4. Differentiating between Various Versions
Tocompare different versions of a file across channels and revisions, use the -r flag to indicate which
revision of the file should be compared and the -n flag to identify the two channels to be checked.
Refer to Section A.2.11 Determining the Number of File Revisions for related instructions. Note that
you specify only one filename here, since you’re comparing the file against another version of itself,
such as:
rhncfg-manager diff-revisions
-n=channel-label1
-r=1
-n=channel-label2
-r=1
/path/to/file.txt
You should see output resembling:
--- /tmp/dest_path/foo.txt 2004-01-13 14:36:41 config
channel: blah2 revision: 1
--- /tmp/dest_path/foo.txt 2004-01-13 14:42:42 config
channel: blah3 revision: 1
