bash ascii to hex

Question

was wondering if anyone could help me with converting ascii to hex in bash. Example code:

#!/bin/bash 
STR = \"hello\"
#Convert to hex
HEXVAL = $STR #(in hex         


        

Answer 1

$ str="hello"
$ hex=$(xxd -pu <<< "$str")
$ echo "$hex"
6C6C6568A6F

Or:

$ hex=$(hexdump -e '"%X"' <<< "$str")
$ echo "$hex"
6C6C6568A6F

Careful with the '"%X"'; it has both single quotes and double quotes.
