Re: [FishMonger] my parameters won't pass through a pipe

OK, I tried a few things. In the script being called if I do this:

Code

print "@ARGV";

then I get back of course the stringified scalar of @ARGV which will be one string. If I do this:

Code

print "$_" for @ARGV;

I get the same thing. If I do this:

Code

print "$_\n" for @ARGV;

and in the other script I have to return the output to a list:

Code

my @testresult = <OUTPUT>;

then everything works as it should and now that I think about it, that's the way it should work. Returning the output of the script to a scalar will only get the first "line" back.

The called script has to print an output record separator and the calling script has to get the results back in a list or using "while".
