问题 Just started learning Python. How can i get a status of file's attributes in Python? I know that os.chmod(fullname, stat.S_IWRITE) delete readonly attribute, but how can i get status without changing it? I need to get all of the attributes of "hidden" , "system" , "readonly" , "archive" 回答1: You can use directly the Windows API like that import win32con import win32api attrs = win32api.GetFileAttributes(filepath) attrs & win32con.FILE_ATTRIBUTE_SYSTEM attrs & win32con.FILE_ATTRIBUTE_HIDDEN

问题 When I use chmod() to change permissions at run time, it gives me the below message: Warning: chmod() [function.chmod]: Operation not permitted in /home/loud/public_html/readalbum.php How can I remove this error and make the chmod function work? 回答1: $ sudo chmod ... You need to either be the owner of the file or be the superuser, i.e., user root . If you own the directory but not the file, you can copy the file, rm the original, then mv it back, and then you will be able to chown it. The

Note that I know about chmod and all, but Linux doesn't seem to provide a fine tuned access permission control where

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . I noticed: chmod -R a+x adds execute permissions to all files, not just those who are currently executable. Is there a way to add execute permissions only to those files who already have an execute set for the user permission? 回答1: Use find : find . -perm /u+x -execdir chmod a+x {} \; 回答2: You can use find to

问题 I have to change the permissions of the htdocs directory in apache to a certain group and with certain read/write/execute. The directories need to have 775 permissions and the files need to have 664. If I do a recursive 664 to the htdocs , then all files and directories will change to 664. I don't want to change the directories manually. Is there any way to change only files or directories? 回答1: Use find's -type option to limit actions to files and directories. Use the -o option to specify

特殊权限 SUID、SGID、Sticky

一 . 前提 本篇主要讲解 SUID, SGID, Sticky 三个权限的基本原理和应用 . 为什么要使用特殊权限 ? 比如系统中假如有超过四类人然而每一类人都需要一种独特权限 . 只有三种独特权限的基础权限系统就会明显不够用 . 特殊权限可以扩展系统基础权限的功能 , 使得 linux 权限更加强大灵活 . 在理解特殊权限之前 , 需要先具备几个关于安全上下文的认知 : 前提:进程有属主和属组;文件有属主和属组; (1) 任何一个可执行程序文件能不能启动为进程:取决于发起者对程序文件是否拥有执行权限; (2) 启动为进程之后,其进程的属主为发起者;进程的属组为发起者所属的组; (3) 进程访问文件时的权限,取决于进程的发起者: (a) 进程的发起者,同文件的属主:则应用文件属主权限; (b) 进程的发起者,属于文件的属组;则应用文件属组权限; (c) 应用文件“其它”权限; 二 . SUID 权限设定方法: 字母表示法 : chmod u+s FILE... chmod u-s FILE... 数字表示法 : chmod 4 755 FILE 添加 SUID 权限到二进制程序文件 (添 加到 DIR 无意义 ) 在普通三位数字权限位之前 , 用 4 代表添加的 SUID 位 chmod 0 xxx .... 可以删除文件的 SUID( 无法删除目录的 SUID ) 文件权限表示

基本权限UGO u 所属主 g 所属组 o 其他人 r (4)读 read w(2)写 write x(1)执行 execute 针对文件: ​ r 读 是否允许可以查看文件的内容 ​ w 写 能够修改或删除文件的内容 ​ x 执行 是否可以执行该文件 一个用户是否能够删除一个文件,判断依据是该用户对该文件所在的目录是否有写的权限 针对目录: ​ r 读 是否允许可以查看目录里的列表 ​ w 写 是否能够删除,重命名目录下的文件和修改目录下文件的属性等 ​ x执行 是否可以进入到该目录 正常操作一个目录,至少应该保证r-x ​ 修改权限 chmod ,修改文件的权限 -R (递归修改)把目录以及目录里的所有子对象都更改 语法: 单独修改一个位置的权限 chmod u-x filename ----将用户的访问或执行权限减去 chmod [u|g|o|a]+-=rwx filename [root@anuo ~]# chmod g=rwx /shared/sysadmin [root@anuo ~]# chmod o=--- /share/sysadmin 修改文件权限语法 chmod [-R] <a|u|g|o> +-= rwx- /<path>/filename chmod [-R] 755 /<path>/filename [root@anuo ~]# chmod 750
