in thread perl unable to locate my module

Um, try
@perl = qw{ /usr/bin/perl -I /internal/charrison }; @program = qw{ /internal/charrison/test }; @args = qw{ -l /internal/charrison -P /internal/charrison }; @cmd = ( @perl, @program, @args ); use Data::Dump; dd( \@cmd ); exec @cmd;
[ "/usr/bin/perl", "-I", "/internal/charrison", "/internal/charrison/test", "-l", "/internal/charrison", "-P", "/internal/charrison", ]

This avoids the shell.

    That seems to have solved the problem. I don't understand how avoiding the shell made any difference, since from what I can make of the exec() doc, involving the shell mainly allows metacharacters to be interpreted.

    However, based on your solution, it appears that the safest way to pass multiple arguments to exec() is in an array of "words" (as defined by qw//).

    Thank you for your help!
