This article is to share with you about how to use the common command lsattr in Linux. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Linux commonly used command lsattr command is used to display file attributes, use chattr execution to change the properties of files or directories, and execute lsattr instructions to query their attributes.

Syntax lsattr [- adlRvV] [file or directory.] Parameters:

-a displays all files and directories, including "." Additional built-in for the first character of the name, the current directory. With the upper directory "..".

-d displays the directory name, not its contents.

-l this parameter currently has no effect.

-R recursive processing, all files and subdirectories under the specified directory are processed together.

-v displays the file or directory version.

-V displays version information.

Example 1. Use the chattr command to prevent a key file in the system from being modified:

# chattr + I / etc/resolv.conf and then manipulate the file with commands such as mv / etc/resolv.conf to get the result of Operation not permitted.

Vim prompts for a W10: Warning: Changing a readonly file error when editing the file. If you want to modify this file, remove the I attribute:

Chattr-I / etc/resolv.conf uses the lsattr command to display file attributes:

# the output result of lsattr / etc/resolv.conf is:

-I-/ etc/resolv.conf2, so that a file can only append data to it, but cannot delete it. It is applicable to various log files:
