Full Discussion: Housekeeping null 2>&1 in /dev
Operating Systems AIX Housekeeping null 2>&1 in /dev Post 303017932 by Don Cragun on Friday 25th of May 2018 02:44:02 AM

Find the process that is writing to it. Kill that process. Remove the file. And, fix the redirection in the process that was writing to it before you restart that process.

The process will be (or will have been) running as root. There will be a redirection in that process that looks something like:
Code:
> "/dev/null 2>&1"

It should be something more like one of the following:
Code:
> "/dev/null" 2>&1
> /dev/null 2>&1

tty

TTY(4)							     Linux Programmer's Manual							    TTY(4)

NAME

       tty - controlling terminal

DESCRIPTION

       The  file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty.  It is a syn-
       onym for the controlling terminal of a process, if any.

       In addition to the ioctl() requests supported by the device that tty refers to, the following ioctl() request is supported:

       TIOCNOTTY
	      Detach the current process from its controlling terminal, and remove it from its current process group, without attaching  it  to  a
	      new  process  group  (that  is,  set  its  process group ID to zero).  This ioctl() call only works on file descriptors connected to
	      /dev/tty; this is used by daemon processes when they are invoked by a user at a terminal.  The process attempts to open /dev/tty; if
	      the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while if the open fails, it is obviously not attached to
	      a terminal and does not need to detach itself.

FILES

       /dev/tty
