In Wolfram cloud
RunProcess@$SystemShell returns the following error:
RunProcess::pnfd: Program /bin/sh not found. Check Environment["PATH"].
and $SystemShell gives
It is true that you cannot execute shell commands in the cloud, but that error seems to come from the package
ProcessLink.m and it can be reproduced in CDFPlayer
why ProcessLink functions give that error? is there something that can be tweaked to make ProcessLink functions to work at least in CDFPlayer?
