Hi,<br><br>I maintain a bunch of kickstart files for a few classes of machines I<br>deal with. A frequent thing happening in the %post section is that<br>some config files get edited in a small way, by either appending or<br>modifying a few lines. I do that using here-documents and sed,<br>respectively.<br><br>Recently, I encountered a situation where I need to insert a few lines<br>into a config file at a *specific* location. I figured, in order to<br>stay consistent with my previous style, I'd use sed *and* here-documents<br>to do the job, but all I could come up was this:<br><br>sed -i 's/\[section_title\]/cat/e' /etc/configfile.conf <<EOT<br>[section_title]<br> foo<br> bar<br> blah<br>EOT<br><br>Is there a way to write something like this without the need to<br>repeat the string '[section_title'' in the here-document ? Something<br>more along the lines of the 'a' sed command instead of 's' ?<br><br>Or am I making this way too complicated ?
