Check out perlop, where it says about qx() (or backticks, ``, which most of us will be more familiar with): In list context, returns a list of lines (however you've defined lines with $/ or $INPUT_RECORD_SEPARATOR), or an empty list if the command failed. By default, that is a newline. So the list returned contains one item per line. The question remains: does your command line return a multiline result? I'm not familiar with what you try to do, so I can't tell. You can easily test in two ways: `@a = qx(COMMANDLINE); print scalar @a;` [download] `$a = qx(COMMANDLINE); print "<plaintext>$a";` [download] The former will print the number of items, the latter will make the browser display the text as plaintext, line wrapping an all. I just hope that yo ucan tweak your command line so that you can get separate lines for the returned items. If not, you can set $/ to whatever string separates the data items.	[reply] [d/l] [select]
