C在外壳程序脚本中将二进制数据转换为十六进制 [英] Cconvert binary data to hexadecimal in a shell script

问题描述

我想将二进制数据转换为十六进制，仅此而已，不要花哨的格式. hexdump似乎太聪明了，它对我来说过格式".我想从/dev/random中获取x个字节，然后将它们以十六进制形式传递.

I want to convert binary data to hexadecimal, just that, no fancy formatting and all. hexdump seems too clever, and it "overformats" for me. I want to take x bytes from the /dev/random and pass them on as hexadecimal.

最好只使用标准的Linux工具，这样就不必在每台机器上安装它(有很多).

Preferably I'd like to use only standard Linux tools, so that I don't need to install it on every machine (there are many).

推荐答案

也许使用xxd:

% xxd -l 16 -p /dev/random
