Using bash variables for range in sed -

- 

sed -n '5,10 p' < /proc/cpuinfo

prints 5-10 lines of file /proc/cpuinfo

i want use 

start=5 end=10 sed -n '$start,$end p' < /proc/cpuinfo

so can change values of start , end form script.

you need use double quotes variable expansion:

start=5 end=10; sed -n "$start,$end p" < /proc/cpuinfo
