What is `ls -l`?

The command ls -l is used in Unix/Linux systems to list files and directories in the current directory in a long format. Here's what it does:

• ls: This is the command to list directory contents.
• -l: This option stands for "long format" and provides detailed information about each file and directory.

Output Details

When you run ls -l, you'll see information such as:

• File type and permissions (e.g., -rw-r--r--)
• Number of links
• Owner name
• Owner group
• File size (in bytes)
• Last modification date and time
• File or directory name

Example

$ ls -l
total 12
drwxr-xr-x 2 user group 4096 Jan  1 12:00 dir1
-rw-r--r-- 1 user group  123 Jan  1 12:00 file1.txt

This output shows one directory (dir1) and one file (file1.txt) with their respective details.
