Hi,<br />
Can I know why the default /etc/passwd permission is set to -r--r--r--?<br />
<br />
Isn't it that any user who login will be able to read all the encrypted password in it? Can I change it to -r--r----- so that no other group can view it. Will it have any impact on others command?<br />
<br />
Thanx.<br />

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
