Question

I have a problem with the following code (Perl/Cygwin)

#!/usr/bin/perl
open FILE, ">", "filename.txt" or die $!;
print FILE "A\n";
print FILE "B\n";
print FILE "C\n";
close (FILE); 
system("xargs echo E < filename.txt");

I want it to invoke echo three times and print

E A
E B
E C

but instead it outputs

E A B C

I have tried various things with the xargs delimiter settings to no avail. Can anyone help?

Try xargs -n1 echo E < filename.txt
