Let's talk about how to set file permissions in linux.

Let's talk about linux's file permission settings-general Linux technology-Linux technology and application information. The following is a detailed description. 1. We want to view the file permissions.

We can use the ls commands we have learned before.

For example, ls-l oo

We can view the oo permissions, for example, drwxr-xr-x.

Step by step, d indicates that the directory rwx indicates the permission of the file owner-r-x indicates the permission of the file group. R-x indicates the permissions of all users.

Okay. Let's take a look at the permission. r is readable. w is writable. x is executable.

Next, we need to change the File Permission.

We use the command chmod.

For example, chmod 777 oo

We changed this object in oo to give him the maximum permission.

2. We want to change the owner and group of the file.

We use chown

Chown kk: kk lll

Let's take a look at this example. kk is the user lll is the file name.
