I have a need to store replacement text for a regex substitution in
a variable. In other words, I have code in a perl script like so::
$foo =~ s/(.*)bar(.*)/$replacement/g;
The $replacement string needs to contain a "reference" to $1. In
other words, the string $replacement will contain the string "$1".
I need to have the $1 string interpreted so that it will be
replaced with the text of the first '(.*)' expression.
You are asking a FAQ.
perldoc -q "expand variables"
