Knowledge base → Setting permissions for files and folders in Linux

To restrict access to files and folders, there are commands that allow you to change the owner and access attributes (read, write, execute)

1. To change the owner of a file or folder, use the command

chown user:group /home/user/temp

1.1 To change the owner of subfolders and files, add the R key, then the change will occur recursively for all

chown -R user:group /home/user/temp

2. To change file access rights, use the command

chmod 640 /home/user/temp

2.1 To recursively change rights, use the R key

chmod -R 640 /home/user/temp

2.2 For example, to change the rights of only all files in subfolders, use the following configuration, where d is the directory

chmod -R 775 $(find . -type d)

2.3 To change the rights of all files including nested ones, where f - files

chmod -R 775 $(find . -type f)
