Re: how bash run by crontab is different from login bash shell?

[Peng Yu]

The things that might serve as a solution is "System Preferences >
Security & Privacy > Privacy > Full Disk Access > "add your app such
as svnX". But I tried to set crontab and bash in Full Disk Access. It
doesn't solve the problem. So that is not the solution.

Does anybody who has Mac OS X 15.16 encounter the same problem? I can
not understand why bash can run correct but `enable` can not run.
