Bash script HELP - Hex to Dec

[TryingMyBest]

Hi, i need help with creating script that converts hex to dec. But without using bc calculator or other methods that could convert it in one line. I need to make something like this script that converts dec to hex.

Thanks!

1. #!/bin/bash
2.
3. declare -r HEX_DIGITS="0123456789ABCDEF"
4.
5. dec_value=$1
6. hex_value=""
7.
8. until [ $dec_value == 0 ]; do
9.
10. rem_value=$((dec_value % 16))
11. dec_value=$((dec_value / 16))
12.
13. hex_digit=${HEX_DIGITS:$rem_value:1}
14.
15. hex_value="${hex_digit}${hex_value}"
16.
17. done
18.
19. echo -e "${hex_value}"
