DOT(1P)			   POSIX Programmer's Manual		       DOT(1P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       dot - execute commands in the current environment

SYNOPSIS
       . file

DESCRIPTION
       The shell shall execute commands from the file in the current  environ‐
       ment.

       If  file	 does not contain a slash, the shell shall use the search path
       specified by PATH to find the directory containing file. Unlike	normal
       command	search, however, the file searched for by the dot utility need
       not be executable. If no readable  file	is  found,  a  non-interactive
       shell  shall  abort; an interactive shell shall write a diagnostic mes‐
       sage to standard error, but this condition shall not  be	 considered  a
       syntax error.

OPTIONS
       None.

OPERANDS
       See the DESCRIPTION.

STDIN
       Not used.

INPUT FILES
       See the DESCRIPTION.

ENVIRONMENT VARIABLES
       See the DESCRIPTION.

ASYNCHRONOUS EVENTS
       Default.

STDOUT
       Not used.

STDERR
       The standard error shall be used only for diagnostic messages.

OUTPUT FILES
       None.

EXTENDED DESCRIPTION
       None.

EXIT STATUS
       Returns	the  value of the last command executed, or a zero exit status
       if no command is executed.

CONSEQUENCES OF ERRORS
       Default.

       The following sections are informative.

APPLICATION USAGE
       None.

EXAMPLES
	      cat foobar
	      foo=hello bar=world. foobar
	      echo $foo $bar
	      hello world

RATIONALE
       Some older implementations searched the current directory for the file,
       even  if	 the  value  of PATH disallowed it.  This behavior was omitted
       from this volume of IEEE Std 1003.1-2001 due to concerns	 about	intro‐
       ducing  the susceptibility to trojan horses that the user might be try‐
       ing to avoid by leaving dot out of PATH.

       The KornShell version of dot takes optional arguments that are  set  to
       the  positional parameters. This is a valid extension that allows a dot
       script to behave identically to a function.

FUTURE DIRECTIONS
       None.
