What is the basic usage of the 'sort' command?

The sort command in Linux is used to sort lines of text files. Here are some basic usages:

1. Sort a file alphabetically:

   sort filename.txt

2. Sort in reverse order:

   sort -r filename.txt

3. Sort numerically (useful for numbers):

   sort -n filename.txt

4. Sort by a specific column (for example, the second column):

   sort -k2 filename.txt

5. Sort and save the output to a new file:

   sort filename.txt -o sorted_filename.txt

These commands will help you organize text data efficiently.
