CompTIA Linux+ XK0-006 (V8) Practice Question

You are writing a Bash script that must alert administrators when the integer variable sessions reaches or exceeds 50. You decide to use the >= comparison operator and want to avoid spawning any external commands so that the check runs quickly on any GNU/Linux distribution. Which one of the following one-line constructs will perform the test correctly without producing a syntax error?

  • if (( sessions -ge 50 )); then echo "High load"; fi

  • if [[ "$sessions" >= 50 ]]; then echo "High load"; fi

  • if [ "$sessions" >= 50 ]; then echo "High load"; fi

  • if (( sessions >= 50 )); then echo "High load"; fi
