wait(1)               UNIX System V(Essential Utilities)                wait(1)


NAME
      wait - await completion of process

SYNOPSIS
      wait [ n ]

DESCRIPTION
      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
      sh(1).

NOTES
      If you get the error message cannot fork, too many processes, try using
      the wait 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.)

      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.
