WAIT(1)								       WAIT(1)

NAME    [Toc]    [Back]

     wait - await completion of	process

SYNOPSIS    [Toc]    [Back]

     wait [ n ]

DESCRIPTION    [Toc]    [Back]

     Wait for your background process whose process id is n and	report its
     termination status.  If n is omitted, all your shell's currently active
     background	processes are waited for and the return	code will be zero.

     The shell itself executes wait, without creating a	new process.

SEE ALSO    [Toc]    [Back]

     sh(1).

CAVEAT    [Toc]    [Back]

     If	you get	the error message cannot fork, too many	processes, try using
     the wait(1) command to clean up your background processes.	 If this
     doesn't help, the system process table is probably	full or	you have too
     many active foreground processes.	(There is a limit to the number	of
     process ids associated with your login, and to the	number the system can
     keep track	of.)

BUGS    [Toc]    [Back]

     Not all the processes of a	3- or more-stage pipeline are children of the
     shell, and	thus cannot be waited for.

     If	n is not an active process id, all your	shell's	currently active
     background	processes are waited for and the return	code will be zero.
