[pm-h] write to empty files

[Mike Flannigan]

I'm not familiar with touch, but can't you just:

1) open the file for appending (>>)
2) print FILEHANDLE "project xyz";


Example:
open OUT, ">>", $outfile or die "$0: open $outfile: $!"; # Or use the 
new way of opening a file
print OUT "project xyz";
