The script should make sure that it don't comment out other occurrences of VirtualHost ServerAdmin,DocumentRoot,ServerName ErrorLog CustomLog. Since this file has multiple entries for the same.
You are a post Graduate in Computer Application.
You are currently working as a system Administrator.
Those two combined should have led at least to a fleeting understanding of available command line tools and rudimentary shell scripting skills.
So please start by posting what you've tried and where you failed.
Else here's some references to help get you started:
sed -e '/./{H;$!d;}' -e 'x;/yumrepo/b' -e d /etc/httpd/conf/httpd.conf|awk '{if (NR!=1) {print "#",$ALL}}'
?
Or
Code:
sed -e '/rhel59/,+4 s/^/#/' -i /etc/httpd/conf/httpd.conf
? (Sorry, can't get this anchored right.)
Thankyou Spawn, We are getting close to our requirement.
I would prefer the First code [sed -e '/./{H;$!d;}' -e 'x;/yumrepo/b' -e d /etc/httpd/conf/httpd.conf|awk '{if (NR!=1) {print "#",$ALL}}'] . As an addition, instead of just printing, I need to actually insert the pound sign to the source file.
Instead of making AWK to print the output, can we have it insert the # ? (Something like I as a switch for sed to insert ?) Not sure though about the syntax and possibility.

Reason: More clarity
Problem is your "anchor" is somewhere in the middle of the vhost container and you're using tools that don't know that the "container" concept. So what you have to do is to detect the start of the container, store any subsequent lines, detect the search string, act on that, detect the end of the container and if the search string was detected then act on it. How you do that depends on what you're comfortable working with. I'd prolly script it.
*And having separate vhost files obviously makes management way easier.

So how about with our first code ? Can we rephrase it to insert pound on the beginning of all lines it prints as output ? Some kind of switch for AWK, to insert the character rather than just printing it out ?
