Hello!I'm trying to do a very simple task: I want to use the 'stat' builtin from BASH_LOADABLES_PATH without overwriting the current behavior of the 'stat' command in the current shell (whether it's a binary from $PATH, or an alias, or a function).
So you want it to override an executable file, since adding a loadable builtin doesn't change the search order, and aliases and shell functions are found before builtins.
This does not work: $ builtin stat bash: builtin: stat: not a shell builtin According to 'help enable' this should work, but it also do not: $ enable stat $ enable -n stat $ builtin stat bash: builtin: stat: not a shell builtin
I'm not sure what you expect -- you just disabled the builtin you loaded, so it won't be used.
'enable -n' should just disable stat, according to 'help enable', but it looks like it also removes it.
Why should it not? You'll have to enable it again before you use it, which will load it again.
So: 1. At least the help for 'enable' should be fixed, but there is definitely a bug in enable+builtin usage for dynamic builtins.
What is the bug?
2. Can you explain how to load and use e.g. stat builtin without overwriting the current behavior of stat in the whole existing script?
Is this anything more complicated than doing
enable it
use it
disable it
