### Julia doesn’t seem to exist and thus doesn’t report CPU usage. I do not know if it is an issue related to the .sh script or to Julia

Pardon-me if it is not Julia related, and let me know, I’ll ask StackExchange instead.

I am using my Julia command within a bash [wrapper to monitor my mean CPU usage](https://superuser.com/a/1848641/942739).

```julia-auto
$ ./script_meanCPUMemory.sh bash -c "julia -t 1 src/script_etudedtsi.jl 80 20 100 366 2 10 5 1 0 0 1 1"

```

The content of `script_meanCPUMemory.sh` can be found in the StackExchange.SuperUser question. Please indicate whether you would like me to post it here in order to make this Julia Discourse question self-contained or not.

The code works like a charm, the following is an extract with some sensitive informations removed

```julia
$ ./script_meanCPUMemory.sh bash -c "julia -t 1 src/script_etudedtsi.jl 80 20 100 366 2 10 5 1 0 0 1 1"

Writing output...

```

You an see that it seems the .bash script doesn’t exit.

Please note that I tried to add `exit()` at the end of `script.etudedtsi.jl` with resulting the same failure:

```julia-auto
EtudeDTSI.launchoptimize(pars)
exit()

```

Only `Ctrl+C` will terminate the process without displaying the final `echo` of the bash script.

Do you know what happens?

Also maybe my problem could be simply solved if there was a package that aims to monitor mean CPU usage instead of using a .bash script. Have you heard of such a package?

Many thanks 😃

Please be aware that the bug has been resolved in SE.SuperUser, so it was not a Julia related question. However, this raises the question of whether there exists, and if not, if there is the need for a package that monitors CPU and Memory usage of a Julia command!

Wishing the best to Julia Discourse’s community 😃

Such a package would be very useful, something like [psutil](https://github.com/giampaolo/psutil/tree/master).
