Breaking "while read" also breaks the parent process
Hi,
I'm a bit confused. Maybe some master can explain to me what is happening.
I have a program that starts issuing output about himself loading.
I want to run it in another thread but I want to wait untill it's fully loaded.
Program sample:
If I run it like this, it will stay in another thread but I will not be sure it is "up and running":
So I tried to run it like this but the process dies very soon : Question: How can I stat myprogram and wait untill it outputs "up and running"?
Dears,
I've written a script which allows me to send mails in different formats with different attaches. Now I still want to add a feature to this script. My users would like to be able to receive a "read" or "delivered" receipt for their mails.

In this post, Perderabo's script says
echo 05/06/25 14:15:56 | IFS=" /:" read Y1 M1 D1 h1 m1 s1
which, if I am not wrong, will break the input into Y1, M1 et al.
I tried the following in my code

hwloc-ps
HWLOC-PS(1) hwloc HWLOC-PS(1)NAME
hwloc-ps - List currently-running processes or threads that are bound
SYNOPSIS
hwloc-ps [options]
OPTIONS -a list all processes, even those that are not bound to any specific part of the machine.
-p --physical
report OS/physical indexes instead of logical indexes
-l --logical
report logical indexes instead of physical/OS indexes (default)
-c --cpuset
show process bindings as cpusets instead of objects.
-t --threads
show threads inside processes. If -a is given as well, list all threads within each process. Otherwise, show all threads inside
each process where at least one thread is bound.
--whole-system
Do not consider administration limitations.
--pid-cmd <cmd>
Append the output of the given command to each PID line. For each displayed process ID, execute the command <cmd> <pid> and
append the first line of its output to the regular hwloc-ps line.
DESCRIPTION
By default, hwloc-ps lists only those currently-running processes that are bound. If -t is given, processes that are not bound but contain
at least one bound thread are also displayed, as well as all their threads.
hwloc-ps displays process identifier, command-line and binding. The binding may be reported as objects or cpusets.
By default, process bindings are restricted to the currently available topology. If some processes are bound to processors that are not
available to the current process, they are ignored unless --whole-system is given.
The output is a plain list. If you wish to annotate the hierarchical topology with processes so as to see how they are actual distributed
on the machine, you might want to use lstopo --ps instead (which also only shows processes that are bound).
The -a switch can be used to show all processes, if desired.
EXAMPLES
If a process is bound, it appears in the default output:
$ utils/hwloc-ps
4759 Core:0 myprogram
If a process is not bound but 3 of his 4 threads are bound, it only appears in the thread-aware output:
$ utils/hwloc-ps
$ utils/hwloc-ps -t
4759 Machine:0 myprogram
4759 Machine:0
4761 PU:0
4762 PU:2
4765 PU:1
To display the binding of already running MPI processes (launched by Open MPI) and append their MPI rank (in MPI_COMM_WORLD) to each line:
$ utils/hwloc-ps --pid-cmd myscript
29093 L1dCache:0 myprogram OMPI_COMM_WORLD_RANK=0
29094 L1dCache:2 myprogram OMPI_COMM_WORLD_RANK=1
29095 L1dCache:1 myprogram OMPI_COMM_WORLD_RANK=2
29096 L1dCache:3 myprogram OMPI_COMM_WORLD_RANK=3
where myscript is a bash script doing:
#!/bin/sh
cat /proc/$1/environ 2>/dev/null | xargs --null --max-args=1 echo | grep OMPI_COMM_WORLD_RANK
