However, A2990_duallayerA_1 is not shortened in any way... Nevertheless, nice code. Some comments would still be helpful for faster understanding.

    To shorten "A2990_duallayerA_1" when "A2990_duallayer_1" is also present would require removing from the middle of the word, and that goes against your examples. You didn't specify your spec, so I had to guess a lot.

    To handle this case, you could consider a lowercase followed by an uppercase to be a word break. Change

    if ($key =~ /^[a-zA-Z]\z/) {

    to

    if ( $key =~ /^[a-z]\z/ || $key =~ /^[A-Z]\z/ && $flux !~ /[a-z]\z/ ) {

    You get:

    A2990_duA_1 A2990_du_1 A2990_du_2 A2990_du_3 A2990_du_4 A2990_du_5 A2990_du_6 A2990_du_7 A2990_du_8 A2990_du_9 A2990_du_10 LXP_01 LXP_02 ...

    Fixed in original code.
