What regular expression do I need to convert Version: 1.2.3 to
Version:
1.2.4 ?
I.e. my pattern is Version: number.number.number and from that i need
Version: number.number.number+1
After the : i can have a space or not...
Why use a regex?
perl -wle '
$v = 2.1.1;
printf "%vd\n", $v;
substr $v, -1, 1, chr ord(substr $v, -1, 1) + 1;
printf "%vd\n", $v
'
See also version.pm
Because a regex works whereas your option doesn't answer the question.
Show how to use this technique to convert "Version: 1.2.3" to
"Version: 1.2.4".
