如何用16进制查找替换文件中的字符？
16进制字符在unix shell里如何表示？
比如 sed 's/0x01/0x10/', 要用0x10替换0x01怎么做？

from bash manual page, `Quoting' section:
Words of the form $'string' are treated specially. The word expands to
string, with backslash-escaped characters replaced as specifed by the
ANSI C standard. Backslash escape sequences, if present, are decoded
as follows:
\a alert (bell)
\b backspace
\e an escape character
\f form feed
\n new line
\r carriage retur
