Hello rsFalse,

perl -le '$_ = "a"; print length . '' ? "A" : "B" '
[download]

The one-liner terminates at the second '. Try using "" for the empty string instead of '' here:

 1:34 >perl -le "$_ = 'a'; print length . '' ? 'A' : 'B'"
A

 1:34 >

(but my single and double quotes are reversed because I’m on Windows.)

Hope that helps,
