# Ensure the frm binary is built

# Generate test data
bash test_data_gen.sh

# Measure time for rm -rf
measure_time "rm -rf ./test_data" "rm_time.txt"
rm_time=$(extract_time "rm_time.txt")

# Regenerate test data

# Measure time for frm

## Results

| Command | Time (s) |
|---------|----------|
| rm -rf  | $rm_time |
| frm     | $frm_time |

## Conclusion

The table above shows the time taken by each command to delete the test data directory. The \`frm\` command is compared against the traditional \`rm -rf\` command.
