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.

PSEUDOFS(9) BSD Kernel Developer's Manual PSEUDOFS(9)NAME
pseudofs -- pseudo file system construction kit
SYNOPSIS
#include <fs/pseudofs/pseudofs.h>
DESCRIPTION
The pseudofs module offers an abstract API for pseudo-file systems such as procfs(5) and linprocfs(5). It takes care of all the hairy bits
like interfacing with the VFS system, enforcing access control, keeping track of file numbers, and cloning files and directories that are
process-specific. The consumer module, i.e., the module that implements the actual guts of the file system, needs only provide the directory
structure (represented by a collection of structures declared and initialized by macros provided by pseudofs) and callbacks that report file
attributes or write the actual file contents into sbufs.
SEE ALSO linprocfs(5), linsysfs(5), procfs(5), sbuf(9), vnode(9)HISTORY
The pseudofs module appeared in FreeBSD 5.0.

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:
$ ls -ld /usr/bin /usr/bin/cat

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)
