Here are some basic Linux commands along with their short descriptions :
The `ls` command in Unix/Linux is used to list directory contents. Here's a basic syntax:
```
#ls [options] [file or directory]
```
Some common options include:
#ls -l : Long format, displaying detailed information about each file or directory, including permissions, ownership, size, and modification time.
#ls -a : Include hidden files and directories, which are those whose names start with a dot (`.`).
#ls -h`: Print sizes in a human-readable format (e.g., 1K, 2M).
#ls -r`: Reverse the order of the sort to get the reverse order.
#ls -t`: Sort by modification time, newest first.
#ls -S`: Sort by file size.
#ls -R`: List subdirectories recursively.
For example, to list all files and directories in the current directory in long format, including hidden files, you can use:
```
#ls -la
```
Or to list all files and directories in the current directory in long format, sorted by modification time with the newest first:
```
#ls -lt
```
There are many more options available. You can find detailed information about the `ls` command in its manual page by typing `man ls` in your terminal.
