Note that only one of the -p or -g flags may be specified when adjusting the state of existing processes. EXIT STATUS The protect utility exits 0 on success, and >0 if an error occurs. EXAMPLES Mark the Xorg server as protected: pgrep Xorg | xargs protect -p Protect all ssh sessions and their child processes: pgrep sshd | xargs protect -dip Remove protection from all current and future processes: protect -cdi -p 1 SEE ALSO procctl(2) BUGS If you protect a runaway process that allocates all memory the system will deadlock.
