I would like to have pledge on the command line so I can restrict an ad-hoc process during execution. For example:
$ pledge "stdio" sed -e "s/foo/bar/g" <input.txt >output.txt I can't modify sed, for example, because I don't always want it pledged that tightly. Since execve removes pledges, I can't see a way to write this pledge utility myself. Is it possible? Is there a better way to impose these kinds of ad-hoc restrictions on a utility? Thanks.
