Can chgrp be used with wildcards?

Yes, the chgrp command can be used with wildcards to change the group ownership of multiple files or directories at once. Wildcards allow you to specify patterns that match multiple filenames.

Example of Using Wildcards:

Change Group for All .txt Files:
To change the group of all text files in the current directory to editors, you can use:
```
chgrp editors *.txt
```
Change Group for All Files in a Directory:
To change the group for all files in a specific directory, you can use:
```
chgrp editors /path/to/directory/*
```
Recursive Change with Wildcards:
If you want to change the group for all files and subdirectories within a directory, you can combine chgrp with the -R option:
```
chgrp -R editors /path/to/directory/*
```

Important Note:

When using wildcards, be cautious as they can match more files than intended. Always double-check the files being affected by using ls with the same wildcard pattern before executing the chgrp command.
