Question: 1 / 400

Which command will give write permission to the hr group for all files in the /hr directory?

chmod g+w /hr/*

The command that gives write permission to the hr group for all files in the /hr directory is the one that uses the `chmod` utility with the `g+w` option. This command modifies the permissions of files by adding write permissions (`w`) specifically for the group (`g`) associated with those files.

The syntax `/hr/*` indicates that the command will apply to all files within the /hr directory. By using `chmod g+w`, it effectively updates the permission settings to include write access for the group's users, enabling them to make changes to the files within that directory.

This is particularly useful in a collaborative environment where a specific group needs to modify shared files. The other options do not achieve this same outcome: some involve changing ownership or listing file permissions without modifying them. This makes the first choice the most appropriate for granting the required permission.
