in reply to -s switch in perl

It is also worth mentioning that using -s in the manner shown is equivalent to:

if (-e /tmp/xyz && !-z /tmp/xyz) {}

i.e. it checks both that the file exists and has non-zero size, which can be useful.

    I think you meant to say: 
    if ( -e "/tmp/xyz" && ! -z _ ) {}

    (quotes around file name, and use of "_" to re-use the most recent stat results, rather than using stat twice in a row on the same file).
