Posix-Shellscriptsは、関数とエラーを生成するコマンドで記述できるため、Bash-Shellscriptよりもエラーが多い傾向があることを述べるのは正しくありません。Posix-Shellscriptsとは異なり、Bash-Shellscriptsは、同じ目的を提供するPosix-Shellスクリプトほど容易にUNIXプラットフォーム間でポータブルではない場合があります。Posix-Shellscriptsは通常、複雑ではなく、複雑なBash-Shellscriptよりもエラーが発生しやすくなります。
Its not correct to state that POSIX-shellscripts are more or less prone to errors than Bash-shellscripts as either can be written with functions as well as commands that generate errors. Unlike POSIX-shellscripts, Bash-shellscripts may not be portable across unix platforms as readily as POSIX-shell scripts that provide the same purpose.  POSIX-shellscripts are usually less complex and so less prone to errors than more complex Bash-shellscripts.
