Shell Programming and Scripting

suppose u have a file
AAAAAKKSKSKMSKMSKBNNSHNKSNJNMSYNMSBH
This is exactly wht the input is like
Question is i want to list wht is on the line 5 tht will be A
but Remember u want to extract in between say from 100 to 300
i tried using
awk 'BEGIN {FS=""} {print$100,$300}' file
but it will print only wht is the line on 100 and 300 so the question is how to grep or extract the line between 100 and 300??
thanks

Er, when you say lines, does that mean that it is actually seperated by '\n'? Or is this all on one line? If it is all on one line, use this:

Code:

awk '{print substr($0,100,200)}' file

For seperate lines, use sed:

Code:

sed -n '100,300p' file
