Question

A user executes the following command successfully: $ chmod +x filetxt. Which of the following is true of the output of this command?

1) The command results in adding execute permission to the user who ran this command
2) The command results in adding execute permission for the owner of the file
3) The command results in an error since the file is not an executable file
4) Cannot be fixed

Answer 1

The command 'chmod +x filetxt' successfully adds execute permission to the owner, the group, and others for the file 'filetxt'. It does not result in an error because of the type of file and does not depend on the file's content. The command is used to change file permissions on a Unix or Linux system.

Step-by-step explanation:

When the chmod +x filetxt command is executed successfully, it applies execute permissions to the file named 'filetxt'. Specifically, this command does the following:

• The command adds execute permission for the user who owns the file (also known as the owner).
• Furthermore, it grants execute permission to others who are not the owner or part of the group.

The command does not result in an error due to the file not being an executable because 'chmod' is designed to change permissions regardless of the file's current type or content. Once the execute permission is granted, the file can be attempted to be run as a script or an executable, assuming it has the appropriate content or format (e.g., a script with a shebang line).
