command not found (using shell)

[garycnew]

I've successfully installed node-0.10.48 and vtop-0.5.7 on a legacy armv7 Linux device. However, when attempting to exec the vtop command I receive a command not found error. After reviewing the vtop wrapper, I'm beginning to believe it's an incompatibility issue with shell (sh). Shell contains the builtin exec command (# type exec), but it doesn't have the builtin command command (# type command). Is this a known compatibility issue? Thank you for your assistance.

I've discovered that I'm able to successfully exec vtop-0.5.5 directly, without the vtop wrapper, but only the cpu and memory graphs work (the pid list is blank). Moreover, is the network graph not incorporated in vtop-0.5.5? Thanks, again, for your assistance.
