A system administrator needs to write a shell script that will output 'Large file detected' if a specified file size exceeds 1024 kilobytes. Which of the following shell script code blocks is the BEST to accomplish this?
if [ $(stat -c%s "file.txt") / 1024 -gt 1024 ]; then echo 'Large file detected'; fi
if [ $(stat -c%s "file.txt") -gt 1024 ]; then echo 'Large file detected'; fi
if [ $(stat -c%s "file.txt") -gt 1048576 ]; then echo 'Large file detected'; fi
if [[ $(stat -c%s "file.txt") -gt 1024 ]]; then echo 'Large file detected'; fi
