How do I use these wildcards?

You can use wildcards in various commands in the terminal to match files and directories. Here are some common examples:

1. Listing Files

• Asterisk (*): To list all .txt files:

  ls *.txt
  

• Question Mark (?): To list files with a specific pattern:

  ls file?.txt
  

• Square Brackets ([ ]): To list files that start with a, b, or c:

  ls [abc]*.txt
  

2. Copying Files

You can use wildcards when copying files:

cp *.txt /destination/directory/

This command copies all .txt files to the specified directory.

3. Moving Files

To move files that match a pattern:

mv file?.txt /destination/directory/

4. Deleting Files

To delete files with a specific extension:

rm *.log

This command deletes all .log files in the current directory.

5. Using Wildcards in Scripts

You can also use wildcards in shell scripts to process files dynamically.

Note:

Be cautious when using wildcards, especially with commands like rm, as they can affect multiple files at once.
