What are common ls options?

Here are some common options for the ls command in Linux:

-l: Long listing format. Displays detailed information about each file, including permissions, owner, size, and modification date.
```
ls -l
```
-a: Lists all files, including hidden files (those starting with a dot).
```
ls -a
```
-h: Human-readable sizes. Used with -l to display file sizes in a more understandable format (e.g., KB, MB).
```
ls -lh
```
-R: Recursively lists all files and directories in the current directory and its subdirectories.
```
ls -R
```
-t: Sorts files by modification time, with the newest files first.
```
ls -lt
```
-S: Sorts files by size, with the largest files first.
```
ls -lS
```
-r: Reverses the order of the sort.
```
ls -lr
```

You can combine these options for more customized output. For example:

ls -lha
