I guess all three options would work. I just tried mhist and it still works with the "FILE" history
mhist -e <equipment name> -v <variable name> -h 10

[quote="Pintaudi Giorgio"]
Hypothetically which one between the two lends itself the better to being "batched"? I mean to be read and controlled by a program/routine. For example,
some programs give the option to have the output formatted in json, etc...[/quote]

Since the beginning of the lockdown I have been working hard on a new object-oriented interface to the online database ODB. I have the code now in an initial

If you load a file into the sequencer from the web interface, you get a list of all files in that directory.
This basically gives you a list of possible sequencer files. It's even more powerful, since you can
create subdirectories and thus group the sequencer files. Attached an example from our

Hi Marius,
your fix is good. Thanks for digging out this deep-lying issue, which would have haunted us if we would not fix it.

Few comments:
- As KO write, we might need semaphores also on a remote front-end, in case several programs share the same hardware. So it should work and cm_get_path() |
