Title
Body
I have a problem with what I think is a difference in grep's regex and perl's regex. Consider the following little test: $ cat testfile.txt A line of text SOME_RULE = $(BIN) Another line of text $ grep "SOME_RULE\s*=\s*\$(BIN)" testfile.txt SOME_RULE = $(BIN) $ perl -p -e "s/SOME_RULE\s*=\s*\$(BIN)/Hello/g" testfile.txt A line of text SOME_RULE = $(BIN) Another line of text As you can see, using the regex "SOME_RULE\s*=\s*$(BIN)", grep could find the match, but perl was unable to update the file using the same expression. How should I solve this problem?
