Sara has asked for the wisdom of the Perl Monks concerning the following question:

Hello guys ,, if I have this
\nb\hot\src\hot2.cpp@@\main\gold\4
I want to use this command called cleardiff for that path as follow:
cleardiff \nb\hot\src\hot2.cpp@@\main\gold\3 \nb\hot\src\hot2.cpp@@\ma +in\gold\4
so what I ma doing is getting the whole line and subtracting the last number by 1 then calling cleardiff for the two path in one command line. I am not sure how to get to the last value .. split doesn't seem to be a solution ,, also =~ s/\.gold\d/\gold\d+1/ not working ,, any easir way .. thanks for help
