How do i grep a pattern from part of LINE
Hi how do i grep only a part of the line from a file from all the lines.


file:
asdfgh 543212376 nag
lkjh abhilash 543757858

How do i grep and print only 543212376 and 543757858

use grep and pipe it thru to either cut or awk

sed may be a better option

Code:
sed 's/^.*\(543[0-9]*\).*$/\1/' file
