Some Suggestions on 'chmod' command |

Dear team,
when using chmod command with '-R' option to set permissions on a directory and
files under the directory, I found that if my changed permissions cause the
current user to lose 'r' or 'x' permissions, then an error will be reported
during execution, resulting in only permission modification to the directory.
The following are my suggestions:
If the user only wants to modify the permissions of the directory, he should
not consider using the '-R' option.
If the user wants to modify the permissions of the directory and all files
under the directory, he should consider using the '-R' option and cannot let
the current user lose the 'r' and 'x' permissions, otherwise even the
permissions of the directory cannot be changed (the current behavior is to
modify at least the permissions of the directory).
If the user only wants to modify the permissions of all files under the
directory (excluding the directory), a command like 'chmod u+x ./target_dir/*'
may be more appropriate.
I hope you can consider my suggestion.
Best wishes,
YuLiang Liu
