This may be an easy idiom that I'm just not thinking of...
I have cases where I'd like to comment out lines in config files that
_don't_ match the new form.
For instance, I want to configure /etc/postfix/main.cf, and set
various fields to partiuclar values...
main_domain = ( cbbrowne.com )
editfiles:
{ /etc/postfix/main.cf
AppendIfNoSuchLine "myhostname=$(main_domain)"
HashCommentLinesContaining "^[^#]*myhostname=(NOT SURE WHAT)"
}
I'm not sure what regex is going to generally match "anything that's
not $(main_domain)".
Note that this idiom is also going to be real useful for /etc/hosts...
