What are wildcards in Linux and how do I use them?
Wildcards in Linux are special characters that represent one or more characters in file names. They are useful for matching patterns.
Can you give me examples of common wildcards?
Sure! The most common wildcards are *
(matches any number of characters) and ?
(matches a single character).
How would I use *
to list all text files in a directory?
You can use the command ls *.txt
to list all files that end with .txt
in the current directory.
What about using ?
? Can you show me an example?
Absolutely! If you have files like file1.txt
, file2.txt
, and fileA.txt
, using ls file?.txt
will match all of them.
