[rancid] Ignoring certain diffs

Discussion:

I went through the archives, and implemented one of the solutions for
ignoring diffs (such as call-forward, etc.).

I implemented it as follows in control_rancid:
<-- snippit -->
if [ $RCSSYS = "cvs" ] ; then
DIFFSUPPRESS="-I '.*call-forward.*' -I '.*Flash.*nvram.*'"

cvs -f diff -u -4 -ko $DIFFSUPPRESS \
| sed -e '/^RCS file: /d' -e '/^--- /d' \
-e '/^+++ /d' -e 's/^$[-+ ]$/\1 /' >$TMP.diff
else
svn diff | sed -e '/^+++ /d' -e 's/^$[-+ ]$/\1 /' >$TMP.diff
<-- snippit -->

Unfortunately this doesn't seem to have worked. I checked my RANCID e-mail
this morning and it shows the following:

Index: configs/<hostname>
===================================================================
retrieving revision 1.4
diff -u -4 -I ''\''.*call-forward.*'\''' -I ''\''.*Flash.*nvram.*'\''' -r1.4

It looks like it should have ignored any lines with "Flash: nvram", yet they
are still showing up.

Can anyone please provide a second set of eyes and help me figure out what
I've done wrong?

Thanks,

If you don't want the flash stuff you could always very simply remove
it from the collection. Most people that I have seen ask that question
do that.

open the corresponding rancid file "for cisco open:
<rancid_home>/bin/rancid" and then search for "commandtable". Comment
out the commands you don't really care for.

A much more ideal solution would be some nice regex during the
collection period that would remove the file size or date/time stamp.
I don't have time at the moment to look at that, but maybe someone
else does and they can offer it up to John to include.

Here is what the e-mail looks like from RANCID, can anyone look at the
syntax and help me figure out what's wrong? Obviously the -I
statements are having no effect (-I '.*Flash.*nvram.*' for example)

diff -u -4 -I ''\''.*call-forward.*'\''' -I ''\''.*Flash.*nvram.*'\'''
-I ''\''.*VTP.*Revision'\''' -I ''\''.*VTP.*MD5'\''' -I
''\''.*Cryptochecksum.*'\''' -r1.3 <hostname.here> @@ -27,15 +27,15 @@

Here's the snippit of control_rancid that calls the -I statements:

I '.*VTP.*MD5' -I '.*Cryptochecksum.*'"
