Top Forums Shell Programming and Scripting awk to remove leading zeros for a hex number Post 302509861 by Chubler_XL on Friday 1st of April 2011 12:27:12 AM

Convert to base 10 using bash/ksh base conversion and back to hex with printf:

Code:
$ printf "%X" $((16#0000000011179E0A))
11179E0A

Edit: Beware - After more testing of the above I found it dosn't work real well with big hex numbers (particularly if first hex digit is > 8), probably best to use string functions to remove the zeros:

Code:
 $ echo 0000000011179E0A | sed 's/^0*//'
11179E0A
