Hi Eric,
Thanks for the help. I'd already "man diff" and it doesn't read like it
applies only to files, but info tells me more :
`-I REGEXP'
`--ignore-matching-lines=REGEXP'
Ignore changes that just insert or delete lines that match REGEXP.
*Note Specified Lines::.
However - this is a *changed* line, not an insert/delete so I don't
think it will work. So my best guess is that I have to pre-grep the
files involved. However this brings me onto the second problem, where
grep seems to have the same issue (unless -f in grep ALSO only filters
filenames..)
I've just tried the same setup using grep in Solaris, and I get the
desired/expected results:
utrannis1 /home/amarsh> cat a.txt
a
b
c
d
e
utrannis1 /home/amarsh> cat b.txt
b
utrannis1 /home/amarsh> /usr/xpg4/bin/grep -f b.txt a.txt
b
But when I try this same thing in cygwins version of grep, it fails
(note the manual grep is ok).
C:\backups\__cisco_backups>cat c.txt
ntp
C:\backups\__cisco_backups>c:\cygwin\bin\grep -f c.txt a.txt
C:\backups\__cisco_backups>c:\cygwin\bin\grep ntp a.txt
ntp clock-period 17179955
ntp source Vlan135
ntp server 135.86.68.147

According to Adrian Marsh on 8/25/2005 3:52 AM:
I've trying to compare two files using diff from a .bat file :
diff -iX scripts/%2.ignorelist "%difffile1%" "%difffile2%"
...
So I wanted to exclude the ntp line and I put it in the ignorelist.
This is not cygwin specific. Read up on 'info diff' - the -X option is a
file listing patterns of FILENAMES to ignore when diffing directories, not
LINES to ignore within file pairs being diffed. Try -I instead.
