[rancid] Re: Ignoring certain diffs

[Eric Cables]

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:
--
DIFFSUPPRESS="-I '.*call-forward.*' -I '.*Flash.*nvram.*' -I '.*VTP.*Revision' -
I '.*VTP.*MD5' -I '.*Cryptochecksum.*'"

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