Bytewave, would you mind explaining what those commands do? I'm not sure about other people, but I certainly wouldn't run some command on my server if I didn't know what it did.
I know they're not malicious since they just use ls, grep, and sed, but someone who didn't know what those commands did might not.
Also: you say it's so long because it's platform independent? I'm not sure if you just mean linux distros, but ls is not a command on windows. I don't believe grep or sed are, either.
