How to list specific files?

To list specific files in Bash, you can use wildcards or character classes. Here are a few methods:

Using Wildcards:

1. Asterisk *: Matches any number of characters.

   ls *.txt  # Lists all .txt files

2. Question Mark ?: Matches a single character.

   ls file-?.csv  # Lists files like file-1.csv, file-a.csv, etc.

Using Square Brackets []:

You can specify a set of characters to match at a specific position.

ls data-[1-3].csv  # Lists data-1.csv, data-2.csv, data-3.csv

Example:

To list files that start with "data-" and end with either "1" or "a":

ls data-[1a].csv  # Lists data-1.csv and data-a.csv

These methods allow you to filter and list specific files based on your criteria. Let me know if you need further assistance!
