Hi Fish,
In my example (there is no metachar), the two forms of system call are the same.
from perldoc -f system:
If there is only one scalar
argument, the argument is checked for shell metacharacters, and if there are
any, the entire argument is passed
to the system's command shell for parsing (this is "/bin/sh -c" on Unix
platforms, but varies on other
platforms). If there are no shell metacharacters in the argument, it is split
into words and passed directly to
"execvp", which is more efficient.
