Hi list, I have a problem with editing/appending to a line in a file where the lense describes nodes in the file as only numbers like /etc/hosts:
[r...@infrastructure-svn ~]# augtool augtool> print /files/etc/hosts /files/etc/hosts/1 /files/etc/hosts/1/ipaddr = "127.0.0.1" /files/etc/hosts/1/canonical = "localhost.localdomain" /files/etc/hosts/1/alias = "localhost" ... /files/etc/hosts/4 /files/etc/hosts/4/ipaddr = "10.10.10.10" /files/etc/hosts/4/canonical = "puppet" What I am trying to do is use a 'set' command to either edit an existing line in the file (based on a pattern match on a 'module' node) or if one does not exist, create a new one. So basically it's an edit operation which appends if it doesn't exist. This can be done one other types of files where base node name is not just a number, /etc/exports for example is "keyed" on the node name 'dir': set dir[.='/home'] /home set dir[.='/home']/client 10.10.10.10 set dir[.='/home']/client/option[1] ro In this way the first 'set' command self-defines if it doesn't already exist, or it edits an existing line. I'd like to achieve the same thing in files where nodes are described like array indexes, but I can't figure out how. Here's a few examples I've tried: augtool> set /files/etc/hosts/*/ipaddr[.='10.44.220.23'] 10.44.220.23 Failed augtool> set /files/etc/hosts/*[ipaddr='10.44.220.23']/ipaddr 10.44.220.23 Failed I'm using Augeas 0.7.3 on CentOS 5.5 and as you would have guessed, through Puppet. I suppose I can always do an 'rm <line>' then 'ins <new>' and use Puppet's onlyif clause to limit when the augeas statements will be run, but it would be nice if it was possible to do it with 'set' commands. I could edit portions of a line matching one of the line's nodes without affecting the rest of the line - this would be very useful for adding extra arguments to lines in /etc/pam.d files without affecting the rest of the line (especially the position). It may be Puppet's use of ruby-augeas that makes this impossible.
