11 months ago A few things:
- It's not really bash though, at least not necessarily:
In [2]: subprocess.call('echo $0', shell=True) /bin/sh
- It's perhaps also worth a warning somewhere that globs, variables, etc, will be expanded.
- I'm personally a fan of distributing small shell scripts alongside PyDM screens as they can be used externally, though I do see the utility here.
- For the designer, it'd be really nice if the shell command could have its own multi-line text edit widget so that you specifically don't have to
chain; commands; together; inan unreadable fashion
allow for Bash features in PyDMShellCommand cmd such as command chaining ("command1; command2")
also add example that shows 2 alternative ways to use Bash through PyDMShellCommand widget.
