Perl script to replace a line after finding a previous line
At the moment I have a flat file which is being used by a few people. I want a script to remotely change the file, so I can start logging who is doing what.
At this point here is one requirement I am trying to develop. We have text blocks who pretty much look like this:
In this text block I first want to find C001 and afterwards change $var3. Thing is, I don't want to change all $var3's.
This is my code so far;
Here are the used variables:
$workflow (C001 as in example given)
$param = $$var3
I hope this is somewhat clear. I try to find $param for the right $workflow and change that. Can you help me to find $$var3 and change that?
There is more than one way to do it
My recommendation is to use a state structure, since this makes it fairly simple to see what is going on.
As for how to change $var3, just remember that, if $var = 'a' you can access $a as $$var, but read the perlreftut and/or perlref manpages for the complete story.
