/bin , /sbin , /usr/sbin , /usr/local/sbin 的区别
usr 是 UNIX Software Resource 的缩写,也就是 Unix操作系统软件资源 所放置的目录。 ? 一 /bin:Essential user command binaries(for use by all users) 1 Purpose /bin contains commands that may be used by both the system administrator and by users,but which are required when no other filesystems are mounted(e.g. in single user mode).It may also contain commands which are used indirectly by scripts. 2 Requirements There must be no subdirectories in /bin, The following commands,or symbolic links to commands,are required in /bin. cat chgrp chmod chown cp date dd df dmesg echo false hostname kill ln login ls mkdir mknod more mount mv ps pwd rm rmdir sed sh stty su sync true umount uname ? 二 /sbin:System binaries 1 Purpose Utilities used for system administration (and other root-only commands) are stored in /sbin,/usr/sbin,and /usr/local/sbin. /sbin contains binaries essential for booting,restoring,recovering,and/or repairing the system in addition to the binaries in /bin. Programs executed after /usr is known to be mounted (when there are no problems) are generally placed into /usr/sbin. Locally-installed system administration programs?should be placed into /usr/local/sbin. ? 2 Requirements shutdown
? 三 /usr/sbin:Non-essential standard system binaries 1 Purpose This directory contains any non-essential binaries used exclusively by the system administrator. System administration programs that are required for system repair,system recovery,mounting /usr,or other essential functions must be placed in /sbin instead. ? ? 四? /usr/local/sbin ? 五 /usr/bin 绝大部分用户可使用命令都放在这里。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
