Difficulty: MediummacOS and Linux Operating System Features and Tools

A system administrator is configuring permissions and group ownership on a Linux server for a script named deploy.sh. The administrator needs to grant read and execute access specifically to the group owner while leaving user and others permissions unchanged. Additionally, the group ownership of deploy.sh must be changed to the webdevs group. Which of the following commands should the administrator execute to accomplish these tasks? (Select TWO.)

  1. chmod g+rx deploy.shAnswer
  2. chgrp webdevs deploy.shAnswer
  3. C
    chown deploy.sh webdevs
  4. D
    chmod 777 deploy.sh

Answer

The administrator must execute 'chmod g+rx deploy.sh' to update group access permissions and 'chgrp webdevs deploy.sh' to reassign group ownership.
Granting specific permissions to a group without altering user or world access requires symbolic permission assignment using 'chmod g+rx'. Changing group ownership independently of user ownership is accomplished using the 'chgrp' command.

Step-by-Step Solution

1
Determine the utility required to add read and execute access for the group owner without altering user or others access permissions.
The symbolic mode command 'chmod g+rx deploy.sh' targets only the group modifier (g) and adds read (r) and execute (x) flags.
Symbolic notation allows targeted updates to specific permission classes without modifying unaffected classes.
2
Determine the command required to update group ownership of the target file.
The command 'chgrp webdevs deploy.sh' changes the group ownership of 'deploy.sh' to the 'webdevs' group.
The chgrp tool specifically alters group ownership independently of user ownership.

Key Concept

Linux file permission modification using symbolic mode and group ownership management.
