Perl: where is the command in system("command -v wget") documented?
I am a perl beginner. I stambled upon a perl line
if (system("command -v wget >/dev/null 2>&1") == 0)
I was able to find perl's documentation for system. But where is
the documentation for command?
Am I right that that line tests whether wget is installed in the
system? How does it do that?
