Hi,
I'm looking into use of rbash/set -r for sourcing and extracting
values
from a script (*). For my usecase, a Bash loadable plugin works for
allowing `source` in such an environment for a limited subset of paths.
I'd like to detect any operation which was denied by `set -r`, but I
don't want to impose `set -e` semantics as it'd be excessive and break
some of the scripts I need to source (which I can't modify for this).
Could any denied operation by way of set -r set some read-only
variable
that I can fetch after sourcing?
I wonder if this would be better suited for a new trap.
Ah, that's a better idea indeed and would work well.
OK, let's put that one on the list.
