This prints nothing perl -le " print for grep 1 .. /Q/, @ARGV " a b c Q r s
This prints nothing $ perl -le " 1../Q/ and print for @ARGV " a b c Q r s
$ perl -le " for( @ARGV ){ print if 1 .. /Q/; }" a b c Q r s
But this does print something, what I expected above code to print
$ perl -le " print for qw/ a b c Q r s / " > what
$ perl -ne " print if 1 .. /Q/; " < what
a
b
c
Q
What am I missing?
