in thread System() in list mode?

What??? Of course it's the correct output for my code. But it's not what I want my code to do. Could you be so kind as to provide me with an example of appending to the PATH variable, then successfully running a script in a path with spaces in it, in one system() call?

    Here I'm prepending $HOME/dir to PATH, and executing a program named "program name", which happens to be in /home/anneli/dir (i.e. the path I prepended):

    $ pwd /home/anneli $ ls -F ./dir/ program name* $ cat dir/program\ name #!/usr/bin/env perl print "It works!\n"; $ cat system('env', "PATH=$ENV{HOME}/dir:$ENV{PATH}", 'program name'); $ perl It works! $

    I hope this helps. We do the necessary expansion of HOME and PATH on our side, before sending them through to the (non-expanding) multi-argument system call.
