CompTIA Linux+ XK0-005 Practice Question

A Linux administrator needs to read user input during the execution of a shell script to capture a username that will be used later in the script. Which built-in command should be used to fulfill this requirement most effectively?

  • Apply grep on the /etc/passwd file to extract a list of usernames.

  • Use read to prompt the user and store the input.

  • Use echo to display a prompt and then capture the user input.

  • Use source to read the username from a separate file.
