Indeed... but what's the equivalent in a system call?

system takes a shell command, so the equivalent of

echo "1 & echo 2 & echo 3" & echo two dos & echo t

using system is

system('echo "1 & echo 2 & echo 3" & echo two dos & echo t');

Do you realize you are launching a Windows build of Perl (ActivePerl or Strawberry Perl?), and that Windows build of Perl launch cmd rather than (non-existent) /bin/sh? In other words,

system('pwd; pwd');
[download]

is the same as

system('cmd', '/x', '/c', 'pwd; pwd');

Perhaps you are looking for

# Adjust the path for your system
system('c:\\progs\\cygwin\\bin\\sh', '-c', 'pwd; pwd');
