値を見つけるために16進ダンプを繰り返します。

ご覧のとおり、hexdump コマンドの出力を確認できます。while-loopたとえば、値を見つけるためにハードディスク全体（またはいくつかの制限）を参照したいとしますAPSB。

私の場合、ステップは4096バイトです。

1. 繰り返し1：hexdump -n 4096 -Cv /dev/disk0s1 -s 0
2. 繰り返し2：hexdump -n 4096 -Cv /dev/disk0s1 -s 4096
3. 繰り返し3：hexdump -n 4096 -Cv /dev/disk0s1 -s 9192

ここに関連しています質問最後の繰り返しについての私の考え。

しかし、hexdump出力で値をどのように見つけることができますか？

可能ですか？

sh-3.2# hexdump -n 4096 -Cv /dev/disk0s1 -s 0
