Execution authority in linux: 1, for a file, the execution permission means that the file has the permission to be executed by the system; 2, for the directory, the execution permission means that the user can enter the directory, and the read-only access to the directory does not allow the use of cd to enter the directory, you must have the permission to execute.

What is the execution permission in linux

The permissions of Linux are not very detailed. There are only three kinds of RWX.

R (Read, read): for files, you have permission to read the contents of files; for directories, you have permission to browse directories.

W (Write, write): for files, it has the permission to add, modify and delete the contents of files; for directories, it has the permission to create, delete, modify and move files in the directory.

X (eXecute, execute): for files, you have permission to execute files; for directories, the user has permission to enter directories.

1. Read-only access to the directory is not allowed to enter the directory using cd. You must have the permission to execute before you can enter the directory.

2. Only the execution permission can only enter the directory and cannot see the contents of the directory. If you want to see the file name and directory name under the directory, you need readable permission.

3. Whether a file can be deleted mainly depends on whether the directory in which the file is located has write permission to the user. If the directory does not have write permission to the user, then all files in the directory cannot be deleted, except the file owner.

4. If the w bit of the directory is not set, even if you have the w permission of a file in the directory, you cannot write the file.
