![]() ![]() When using sudo, script privileges are elevated, which can be dangerous if the script is not properly written or if it accesses sensitive parts of the system.įinally, remember that modifying ownership and permissions on system directories or files should be done with caution, as it can lead to security risks if not handled properly. ![]() The fact that you didn’t try this, might indicate that you don’t know the true power of sudo. Use sudo before the command to run the script as the root user, which typically has more permissions. Run the Script with Appropriate Privileges: If changing ownership or permissions is not possible, you can try running the script with elevated privileges. Check the NAS settings or consult the NAS documentation for any specific limitations. Overview When we work with directories in the Linux command line, we sometimes need to know the last modification time of a directory. It’s generally better to use more restrictive permissions based on your specific use case.Ĭheck the NAS Settings: If the NAS drive has specific settings or restrictions on modifying files, you might need to configure it to allow the user to modify files. find /Documents -name '.py' -type f -mtime 14. So, presumably when I type something like. ctime - changed time last time file inode was modified. mtime - modified time last time file contents was modified. atime - access time last time file opened. Also, don’t try this if you aren’t a system admin, but somehow still have rights to do so.Ĭhange the permissions of the directory/file, you can use:īe careful when using chmod 777, as it provides full read, write, and execute permissions to everyone. So, I understand the difference between the three ideas in the title. Please note, I don’t know why, but I can never get chown right and always need to google it or something, but it is something along this line. Sudo chown your_username:your_groupname targetDirTo Dear All, In the linux platform, is there anyway I can in a C program change. Ensure that the user running the script has write permissions, shown as w for both the target directory and file.Ĭhange ownership or the permissions: If the target directory or file is owned by another user or has restrictive permissions, you can change the ownership or permissions using the chown and chmod commands.To change the ownership of a directory/file, you can use: os.utime(path,times) throws error: OSError: Errno 13 Permission denied. You can use the ls -l command on the command line to check the permissions of the target directory and file. To set the file’s modified time using os.utime, the process needs to have write permissions on the target file.Ĭheck Permissions: Make sure the user running the program has write permissions on the target directory and file. The PermissionError you encountered is probably due to insufficient permissions to modify the target file or directory. ![]()
