Hexadecimal To Decimal in Shell Script

Question

Can someone help me to convert a hexadecimal number to decimal number in a shell script?

E.g., I want to convert the hexadecimal number bfca3000 to deci

Answer 1

Dealing with a very lightweight embedded version of busybox on Linux means many of the traditional commands are not available (bc, printf, dc, perl, python)

echo $((0x2f))
47

hexNum=2f
echo $((0x${hexNum}))
47
