One of the best features of cfengine is its editfiles action/section. Did anybody every rip this out of cfengine and made a standalone commande line tool just to edit files? Or is there any other command tool with simillar functionnality to editfiles that exist out there?


I believe you want this:

http://www.oreilly.com/catalog/sed2/

Ok, I am not very familiar with sed and awk, but as far as I know, these programs are line oriented.

How can I write a script that would perform something like the following and would remain as elegant?

      BeginGroupIfNoLineMatching "# Addition by EMC ended."
        LocateLineMatching ".*. /etc/init.d/functions.*"
        IncrementPointer   "-3"
        InsertLine "# Addition by EMC started."
        InsertLine 'DHCP_HOSTNAME=${dollar}{HOSTNAME}'
        InsertLine "# Addition by EMC ended."
        InsertLine ""
      EndGroup

Off course, this can be done, but I do not know of any scripting tool that allows one to express the above changes so elegantly. Anybody can translate this into sed/awk in about the same number of lines?
