This solves both your problems (if I interpret you correctly):
foreach my $file (grep { !-e } @files) # The grep returns all the elem
+ents of the array
# for which the sub ( { !-e } )
+ returns true, which it
# will only if $_ (the array el
+ement being tested) does not
# exist. If you want it to exi
+st and be a
# regular file (as opposed to a
+ directory, FIFO, etc.)
# use -f.
{
local *FH; # To make sure we don't clobber
+ FH.
open FH, ">>$file"; # In case the file got created
# in the meantime, we use the a
+ppend operator to avoid
# clobbering data.
close FH; # And then we close it.
}
