Linux Shell Programming: Converting hex to binary

What about:

• You have to convert a hex value into a binary value
• Your only tool is a linux shell
• You have to start in 30s
• You have to do it for >10000 hex values

Write a small program in c or java or whatever you would prefer?

What about this:

schroff@hades:$ echo "ibase=16;obase=2; 10 "|bc
10000
schroff@hades:$ echo "ibase=16;obase=2; 1F "|bc
11111

ibase: base of input value
obase: base of output value
The following bases can be used:

• 16 -> hex
• 10 -> decimal
•  8 -> octal
•  2 -> binary
