CompTIA Linux+ XK0-006 (V8) Practice Question

A shell script compares two configuration files by running

diff -q /configs/httpd.conf.orig /etc/httpd/conf/httpd.conf >/dev/null

The script must later test the command's exit status to decide whether to deploy the new file, notify the administrator, or log an error. In what order will the three distinct exit-status values be returned by diff when the files are (1) identical, (2) different, and (3) when an error such as an unreadable file occurs?

  • 0, 1, 2

  • 0, 1 (any difference or error); no separate error code

  • 1, 2, 0

  • 0, 2, 1
