I need a regex to remove zeros after the . in a file name if they are
followed by another digit.
Example: XXXXXX.001 becomes XXXXXX.1
s/\.0+(?=[1-9])/./;
That rewrites the dot, and won't handle ".000".
I would write it like
s/(?<=\.)0+(?=[0-9])//;
Okay...
1. Why is rewriting so bad? Personally I need to look up those extended
patterns, and letting the s/// operator rewrite a single dot is easier
to read IMO.
2. The OP said "another" digit, which I interpreted as a non-zero digit.
I may have been wrong...
