A.2.3. Differentiating between Latest Config Files
To obtain a difference between the config files on disk and the latest revisions in a channel, issue the
command:
rhncfg-manager diff
--channel= channel-label
--dest-file= /path/to/file.txt
/local/path/to/file
You should see output resembling:
/tmp/dest_path/foo.txt /home/test/blahhello_world.txt
--- /tmp/dest_path/foo.txt
config_channel: blah revision: 1
+++ /home/test/blah/hello_world.txt 2003-12-14 19:08:59.000000000
-0500
@@ -1 +1 @@
-foo
+hello, world
A.2.4. Differentiating between Various Versions
To compare 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
