xxd  creates a hex dump of a given file or standard input.  It can also
convert a hex dump back to its original binary form.  Like  uuencode(1)
and  uudecode(1)  it allows the transmission of binary data in a `mail-
safe' ASCII representation, but has the advantage of decoding to  stan‐
dard output.  Moreover, it can be used to perform binary file patching

➜  ~ echo 'hello,world' > origin.txt

# 将文件内容转换为十六进制内容
➜  ~ xxd origin.txt
00000000: 6865 6c6c 6f2c 776f 726c 640a            hello,world.

# 将十六进制内容恢复到一个新文件中
➜  ~ xxd origin.txt |xxd -r > new.text
➜  ~ cat new.text 
hello,world

xxd还支持将文件转换成二进制，格式化输出等。具体可查看官方文档
