Escape a dollar sign inside a variable

Question

I have a simple line of Perl

s/$var/'string'/g

The issue is that $var contains a string like jkdlsf$lkjl. Note the dollar sign in the middle. It seems because of this dollar sign the replace is not working. How do I escape this when it is inside a variable?

Answer 1

Use the \Q quote:

s/\Q$var/'string'/g
