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

问题描述

问这个问题(听起来很基础)有点愚蠢，但是在其他地方找不到答案.我想将二进制数据转换为十六进制，仅此而已，不要花哨的格式化等等. hexdump似乎太聪明了，对我来说它过格式".我想从/dev/random中提取x个字节，然后将它们作为十六进制传递.

feel a bit stupid asking this (sounds as basics) but can't find an answer elsewhere. I want to convert binary data to hex, just that, no fancy formatting and all. hexdump seems too clever, it "overformats" for me. I want to take x bytes from the /dev/random and pass them on as hex.

最好只使用标准的linux工具，这样我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
