PROCCTL(8) BSD System Manager's Manual PROCCTL(8)NAME
procctl -- clear procfs event flags
SYNOPSIS
procctl pid ...
DESCRIPTION
The procctl utility clears the procfs(5) event mask used by truss(1). This can be used in the event that a process is left stranded, since
the procfs(5) events result in a non-killable process. The arguments are a list of process IDs; procctl goes through the list and clears the
event masks for each specified process.
SEE ALSO truss(1), procfs(5)HISTORY
The procctl utility was written by Sean Eric Fagan for FreeBSD.

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
SEE ALSO procctl(2)BUGS
If you protect a runaway process that allocates all memory the system will deadlock.

Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
