Changes include: - Replaced [[ ... ]] with [ ... ] - Replaced == with = - Replaced printf -v with cur=$(printf ...). - Replaced echo -e with printf "%b\n" ...
The above mentioned are Bash/GNU extensions and are not part of POSIX. Using shells like dash or non-GNU coreutils may produce errors. They have been replaced with POSIX-compatible alternatives.
