in thread Problem with substr

$name =~ s/.replaced//;

Note that the  . (dot) in the quoted regex is the metacharacter for the operation "match any character except a newline" and as such will occasionally fail to do what newbie1991 wants. I suggest something like
    $name =~ s/\.replaced//;
in which the dot is escaped to remove its meta-magic and make it match only a lowly period.

>perl -wMstrict -le "my $name = 'e.coliXreplaced'; $name =~ s/.replaced//; print qq{'$name'}; " 'e.coli'
