Python to view the read and write permissions of files, python to read and write

Example:

# -*- coding: utf-8 -*-# @author flynetcnimport sys, os, pwd, stat, datetime;LOG_FILE = '/var/log/checkDirPermission.log';nginxWritableDirs = ['/var/log/nginx','/usr/local/www/var',];otherReadableDirs = ['/var/log/nginx','/usr/local/www/var/log',];dirs = [];files = [];def logger(level, str):logFd = open(LOG_FILE, 'a');logFd.write(datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')+": "+("WARNING " if level else "NOTICE ")+str);logFd.close();def walktree(top, callback):for f in os.listdir(top):pathname = os.path.join(top, f);mode = os.stat(pathname).st_mode;if stat.S_ISDIR(mode):callback(pathname, True);walktree(pathname, callback);elif stat.S_ISREG(mode):callback(pathname, False);else:logger(1, "walktree skipping %s\n" % (pathname));def collectPath(path, isDir=False):if isDir:dirs.append(path);else:files.append(path);def checkNginxWritableDirs(paths):uid = pwd.getpwnam('nginx').pw_uid;gid = pwd.getpwnam('nginx').pw_gid;for d in paths:dstat = os.stat(d);if dstat.st_uid != uid:try:os.chown(d, uid, gid);except:logger(1, "chown(%s, nginx, nginx) failed\n" % (d));def checkOtherReadableDirs(paths, isDir=False):for d in paths:dstat = os.stat(d);if isDir:checkMode = 5;willBeMode = dstat.st_mode | stat.S_IROTH | stat.S_IXOTH;else:checkMode = 4;willBeMode = dstat.st_mode | stat.S_IROTH;if int(oct(dstat.st_mode)[-1:]) & checkMode != checkMode:try:os.chmod(d, willBeMode);except:logger(1, "chmod(%s, %d) failed\n" % (d, oct(willBeMode)));if __name__ == "__main__":for d in nginxWritableDirs:walktree(d, collectPath)dirs = dirs + files;checkNginxWritableDirs(dirs);dirs = [];files = [];for d in otherReadableDirs:walktree(d, collectPath)checkOtherReadableDirs(dirs, True);checkOtherReadableDirs(files, False);

OS. the chmod (path, mode) method should be very simple. It only requires two parameters: path and path mode, the following lists some common modes that can be used in this usage:

Stat. S_ISUID: Set user ID on execution. not commonly used

Stat. S_ISGID: Set group ID on execution. not commonly used

Stat. S_ENFMT: Record locking enforced. not commonly used

Stat. S_ISVTX: Save text image after execution. Save the text and image after execution.

Stat. S_IREAD: Read by owner. Read Permission for the owner

Stat. S_IWRITE: Write by owner. Write Permission to the owner

Stat. S_IEXEC: Execute by owner. permission on the owner

Stat. S_IRWXU: Read, write, and execute by owner. Read and write Permissions Of the owner

Stat. S_IRUSR: Read by owner. Read Permission for the owner

Stat. S_IWUSR: Write by owner. Write Permission for the owner

Stat. S_IXUSR: Execute by owner. permission on the owner

Stat. S_IRWXG: Read, write, and execute by group. Read and write permissions for people in the same group

Stat. S_IRGRP: Read by group. Read Permission for the same group

Stat. S_IWGRP: Write by group. Write Permission for the same group

Stat. S_IXGRP: Execute by group. Permission for execution in the same group

Stat. S_IRWXO: Read, write, and execute by others. Read and write permissions for other groups

Stat. S_IROTH: Read by others. Read Permission for other groups

Stat. S_IWOTH: Write by others. Write Permission for other groups

Stat. S_IXOTH: Execute by others. Permission to Execute other groups

The above Python Method for viewing the file's read and write permissions is all the content shared by the editor. I hope you can give us a reference and support the help house.
