Hello, I would like to suggest and offer the code to extend chmod in a small way. My extension don’t affect referenced file of symbolic links, just avoid them silent.
I need this ability, because I have a problem like this: Some times we need to change mode of files in a directory recursively with root privilege. For example, the directory “/opt/xxxx”, I have installed many files in the directory, and files have different owner and mode. Some mode and owner of files are wrong, so I need to fix them by a program with root privilege. For security reason, we don’t want to affect files not in that directory, like “/etc/passwd”. Then, I found ‘-h’ parameter in “chown”, it help me to protect “/etc/passwd”, but in “chmod”, there is not similar parameter not to dereference symbolic links. The patch is to provide “-h” in chmod, it works similar to it in “chown”. If the object file is a symbolic link, chmod skip it, and move to next file with “-h”. parameter. Because my system is ubuntu 22.04, it can not install vc-dwim. I have to make the patch by git directly. Nan Meng.
