easy substitute question

[theSeeker03]

ok, for some reason I could not find this example in O'Reily book.

I want to substitute every string of "==" to be "|", in $_

so I say:

s/==/|/;

but that only substitutes the first occurence of "==", not all of them. How do you substitute all of them?

You use the [tt]g[/tt] modifier to the regexp.

s/==/|/g;
