XK0-006 Automation, Orchestration, and Scripting Practice Question
An administrator is writing a bash script that loops through all .log files in /var/log and prints the file name if the file is larger than 100 kilobytes. Which loop correctly implements this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
find /var/log -name '*.log' -size +100k -exec echo {} \;
The find command with -size filters files larger than 100k, and -exec with {} runs the command for each file. The other options have syntax errors or incorrect logic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
ls -l /var/log/*.log | awk '$5>100 {print $NF}'
Why it's wrong here
This works for some cases but may fail with spaces in filenames or if ls output changes.
- ✗
for f in /var/log/*.log; do if [ -s $f -a $(stat -c%s $f) -gt 100 ]; then echo $f; fi; done
Why it's wrong here
-s checks if file is non-empty, not size; -gt compares numbers but stat output may cause issues.
- ✓
find /var/log -name '*.log' -size +100k -exec echo {} \;
Why this is correct
Correct. find with -size +100k matches files larger than 100 kilobytes.
- ✗
for f in /var/log/*.log; do if [ $f -gt 100k ]; then echo $f; fi; done
Why it's wrong here
The test command cannot compare file sizes directly; -gt is for integer comparison.
