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 need the value of hexVal to be returned as:
0x000bd8
text-processing grep

Are those values always last words in the line?

Instead of grep, you could use awk as it is more useful in pattern matching and printing out the matched fields
mmc extcsd read /dev/mmcblk1 | awk -F: '$1 ~ "^""Max Enhanced Area Size" print $2 '
You could also remove the leading space in the above result
awk -F: '$1 ~ "^""Max Enhanced Area Size" sub(/^[[:space:]]/,"",$2); print $2 '
