CompTIA Linux+ XK0-006 (V8) Practice Question

Consider the following excerpt from a disk-usage monitoring script:

#!/usr/bin/env bash
warn_level=80
usage=$(df -P / | awk 'NR==2 {print $5}' | tr -d '%')

if [[ $usage -ge $warn_level ]]; then
    echo "Disk space critical"
fi

Which statement correctly describes what the -ge test operator is doing in the condition?

  • The condition becomes true when the integer value in usage is greater than or equal to warn_level.

  • The condition becomes true only when usage is strictly greater than warn_level; equality makes it false.

  • The test requires both operands to be floating-point numbers; with integers it always evaluates to false.

  • The test compares the two operands as strings, so values are evaluated lexicographically rather than arithmetically.
