WAITPID(1)                       User Commands                      WAITPID(1)

NAME
       waitpid - utility to wait for arbitrary processes

SYNOPSIS
       waitpid [-v] [--timeout|-t seconds] PID[:inode]...

DESCRIPTION
       waitpid is a simple command to wait for arbitrary non-child processes.

       It exits after all processes whose PIDs have been passed as arguments
       have exited.

       Optionally, a process can be addressed with the format PID:inode. The
       inode identifies the unique process's file descriptor. To retrieve a
       process's inode number you can use the getino(1) utility.

       -t, --timeout seconds
           Maximum wait time.

       -e, --exited

       -c, --count count
           Number of process exits to wait for.

       -h, --help
           Display help text and exit.

       -V, --version
           Display version and exit.

       waitpid has the following exit status values:

       0

       1
           unspecified failure
