Ascii/Hex convert in bash

Asked 2011-04-20T02:00:50.727

I'm now doing it this way:

[root@~]# echo Aa|hexdump -v
0000000 6141 000a                              
0000003
[root@~]# echo -e "\x41\x41\x41\x41"
AAAA

But it's not exactly behaving as I wanted,

the hex form of Aa should be 4161,but the output is 6141 000a,which seems not making sense.

and when performing hex to ascii,is there another utility so that I don't need the prefix \x ?

bash ascii hex

I don't know how it crazy it looks but it does the job really well

ascii2hex(){ a="$@";s=0000000;printf "$a" | hexdump | grep "^$s"| sed s/' '//g| sed s/^$s//;}

Created this when I was trying to see my name in HEX ;) use how can you use it :)
