Shachar, you wrong. Gilad wants the `diff' program to see "$ID" not
"\$ID" which is what '\$ID' gives to the application (diff does not
substitute $ID with its environment value, bash does it).
Last time I checked, "$" in regexp meant "match end of line". '$Id'
would mean, if I understand this correctly, an "Id" coming AFTER the end
of the line (an impossible combination, I know, but still). If I want
grep to understand a literal "$", I need to pass it a "\$", which I can
do either by doing "\\\$Id" or '\$Id'.
I stand by my original statement.
