Substituting a dot

[LuckyKoen]

I have $string that contains "1.2.3"

I would like to get the . out but with $string =~ s/./_/g the numbers are also replaced with _ instead of only the dots.

How do I make sure that only the dots are replaced and not every character in $string ?

For regexs, '.' means any single character, but if you escape it ('\.') it's a literal period. Try:

$string =~ s/\./_/g;

try this one

$string =~ s/\./_/g;

greetz,

R.

This works, thanks

Since it's single-character replacement you need, it's possibly better with a straight transliteration, rather than a regexp:

$string =~ tr/./_/;

Don't let looks deceive you - it's not a regexp - hence why I haven't escaped the dot, as it has no special meaning.
