Post #1 of 2
i'd like to detect all the lines that their first alpha-numeric word repeats more then once.
for example: this line would be 'hits'
abc sda asd asd abc
aaa bbb ccc aaa aaa
unfortunately i only find how to do it in more than one code line.
meaning that at first i extract the first word, and then i make the replacements.
$string =~ m/(\w+)/;
$string =~ s/$1/$replace_string/;
i don't know how to count the number of occurrence of the first line. so i'll hit only the lines that their first word repeats itself at some point.
i also believe that there is more elegant way to do it.
