How to check directory contents?

To check the contents of a directory in Linux, you can use the ls command. Here are some common usages:

1. Basic Listing:

   ls

   This command lists the files and directories in the current directory.

2. Detailed Listing:

   ls -l

   This command provides a detailed view, including file permissions, number of links, owner, group, size, and modification date.

3. Including Hidden Files:

   ls -a

   This command lists all files, including hidden files (those starting with a dot).

4. Detailed Listing with Hidden Files:

   ls -la

   This combines both options to show all files with detailed information.

5. Listing a Specific Directory:

   ls /path/to/directory

   Replace /path/to/directory with the actual path to the directory you want to check.

6. Sorting by Modification Time:

   ls -lt

   This lists files sorted by modification time, with the most recently modified files first.

You can combine options as needed to customize the output.
