I am writing a bash script and I need to filter out some hexadecimal value from a return string of a command in bash for example:



hexVal=`mmc extcsd read /dev/mmcblk1 | grep 'Max Enhanced Area Size'`


Will return the value of hexVal as:



Max Enhanced Are Size [MAX_ENH_SIZE_MULT]: 0x000bd8


Now, I want the value of hexVal to be returned as:



0x000bd8





bash hex
