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? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
