readproctitle(8)					      System Manager's Manual						  readproctitle(8)

NAME

       readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).

       readproctitle is available in daemontools 0.75 and above.

SYNOPSIS

       readproctitle L D

DESCRIPTION

       L consists of any number of arguments.  D is one argument consisting of at least five dots.

       readproctitle  reads  data  into  the  end  of  D,  shifting D to the left to make room. This means that the most recent data is visible to
       process-listing tools such as ps(1).  readproctitle always leaves three dots at the left of D.

       For example, if

	readproctitle io errors: ....................

       reads the data

	fatal error xyz
	warning abc

       then its command-line arguments change to

	readproctitle io errors: ... xyz!warning abc!

       with a newline character in place of each !. Process-listing tools typically show the newline character as ? or 
.

       readproctitle exits when it reaches the end of input.

       Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle  L	D.
       I have not seen a system with a limit below 512 bytes.
