What are other wildcard characters?

In addition to [abc], there are several other wildcard characters commonly used in Linux and command-line interfaces:

1. Asterisk (*): Matches any number of characters (including none).

   • Example: *.txt matches all files with a .txt extension, like file1.txt, notes.txt, etc.

2. Question Mark (?): Matches exactly one character.

   • Example: file?.txt matches file1.txt, fileA.txt, but not file10.txt.

3. Braces ({}): Used to specify a set of options.

   • Example: file{1,2,3}.txt matches file1.txt, file2.txt, and file3.txt.

4. Exclamation Mark (!): Inside square brackets, it negates the character class.

   • Example: file[!abc].txt matches files that do not have a, b, or c as the next character.

Summary

These wildcard characters allow for flexible and powerful file matching and manipulation in the terminal.
