protect

PROTECT(1)						    BSD General Commands Manual 						PROTECT(1)

NAME

     protect -- protect processes from being killed when swap space is exhausted

SYNOPSIS

     protect [-i] command
     protect [-cdi] -g pgrp | -p pid

DESCRIPTION

     The protect command is used to mark processes as protected.  The kernel does not kill protected processes when swap space is exhausted.  Note
     that this protected state is not inherited by child processes by default.

     The options are:

     -c 	 Remove protection from the specified processes.

     -d 	 Apply the operation to all current children of the specified processes.

     -i 	 Apply the operation to all future children of the specified processes.

     -g pgrp	 Apply the operation to all processes in the specified process group.

     -p pid	 Apply the operation to the specified process.

     command	 Execute command as a protected process.

     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

BUGS

     If you protect a runaway process that allocates all memory the system will deadlock.
