Have a need to schedule programs that can run after other programs are completed. Here's the catch:
1) The list of programs will not always be the same (kind of a plug-n-play deal)
2) The invoking shell may not be the same as the shell of the program being waited on
In other words, I need... (2 Replies)

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.
Is there any other way to watch completion of any, not related process (at least, a process, owned by the same user?)

wait
WAIT(1) BSD General Commands Manual WAIT(1)NAME
wait -- await process completion
SYNOPSIS
wait [pid]
DESCRIPTION
If invoked with no arguments, the wait utility waits until all existing child processes in the background have terminated.
Available operands:
pid If a pid operand is specified, and it is the process ID of a background child process that still exists, the wait utility waits until
that process has completed and consumes its status information, without consuming the status information of any other process.
If a pid operand is specified that is not the process ID of a child background process that still exists, wait exits without waiting
for any processes to complete.
The wait utility exits with one of the following values:
0 The wait utility was invoked with no operands and all of the existing background child processes have terminated, or the process
specified by the pid operand exited normally with 0 as its exit status.
>0 The specified process did not exist and its exit status information was not available, or the specified process existed or its exit
status information was available, and it terminated with a non-zero exit status.
If the specified process terminated abnormally due to the receipt of a signal, the exit status information of wait contains that termination
status as well.
STANDARDS
The wait command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
