In the Linux system, users can use dir and ls commands when viewing directory contents, but the ls command is often used and is listed as the preferred command by many users.

1. Running the ls command without any parameters will list the contents of the current working directory:

* *

2. To list the contents of any directory, for example, the / etc directory uses the following command:

$ls / etc

3. A directory always contains some hidden files (at least two), so to display all files in the directory, use the-an or-all flag:

$ls-a

4. You can also print the details of each file output, such as file permissions, number of links, owner name and group owner, file size, last modified time, and file / directory name:

This is set by the-l option, which means a list format as long as the screenshot below.

$ls-l

Sort files based on date and time

1. To list files in a directory and sort the date and time of the last modification, use the-t option in the following command:

$ls-lt

2. If you want a reverse sorting file based on date and time, you can use the-r option to work like this:

$ls-ltr
