chnorm

Chnorm is a simple command line utility which makes one able to set the owner, group and the mode of the specified files and directories on a per file / per directory basis, recursively.

It is especially useful if you often copy files with braindead permissions from filesystems not supporting the Unix permission scheme. chnorm detects executables based on their contents and sets their permissions accordingly.

Installation

Just copy the chnorm executable into /usr/local/bin , /usr/bin , ~/bin or any path you want but preferably to one that is present in your $PATH environment variable.

You may also want to SUID root this utility by executing chmod +s chnorm.

Usage

$ ./chnorm
Usage: chnorm [OPTION]... [FILE]...
Change the permissions of directories and files distinctively.
