awk: Increment number with leading zeroes

I've gone through many awk questions here on SO, but still can not create one for my purpose.

I have a file like such:

Project Name
Version 1.0
Revision 0059

How do I increment 0059 to 0060 while keeping the rest the same?

Try this

sed -rne '/^Revision/s/Revision ([0-9]+)/\1/gp' temp.txt | awk '{printf("%04d\n",$0+1)}'

One way:

$ awk '$1=="Revision"{$2=sprintf("%04d",$2+1);}1' file
Project Name
Version 1.0
Revision 0060
