WAIT(1)             RISC/os Reference Manual              WAIT(1)



NAME
     wait - await completion of process

SYNOPSIS
     wait [ n ]

DESCRIPTION
     wait waits for your background process whose process ID is n
     and reports 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 pro-
     cess.

SEE ALSO
     sh(1).

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

     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 of your shell's
     currently active background processes are waited for and the
     return code will be zero.
