Dear List
I need to collect bulk data files from some remote machines into my local
machine. I will be using a perl script to read about the remote machines
directory listing from where I will get the source data files.The remote
machines' directory listing from where I will get the data files
I use SCP. About faster or not, it depends on the bandwidth in both
locations and load CPU in each locations.

I am really going crazy here. I have the following system call that I
would like to run from perl:
ls *.txt | xargs cat out
if *.txt does not exist then I expect to get an exit code different
from 0.
So to test I do:
use strict;
my $f = file_which_does_not_exist;
# method 1
print test 1\n;
This is because you send ls's output to a pipe, and the command on the
right of the pipe get executed successfully.
Try this test on shell:
-bash-3.00$ ls |xargs cat
ls: : No such file or directory
-bash-3.00$ echo $?
0
-bash-3.00$ ls
ls: : No such file or directory
-bash-3.00$

- is used for any references. And for method calls. In this case you
are calling the next() method of the $topIter object.

Thank you very much for explaining. I will try what Sandy suggested.
I had tested at the command line already just as Jeff did. The
confusion came from the fact that I had tried it in csh and in csh,
doing the ls |xargs cat returned 1. Annoying.
