try with egrep or with small e
I got something unusual:
I tried the command it works, but after put in script, it doesn't work.

Code:
 else
           echo "I am here"
           echo "print this result" `egrep -v -e '^(END|START)' input` " let see"
           echo "I am after you"
           #egrep -v -e '^(END|START)
           #sed -e '/^ALL/d' -e '/^FILE/d' < input > input_tmp

I got below result:
Code:
I am here
print this result  let see
I am after you

any idea about this?

Thanks

can you post your input file ?

try without Grave accents

Code:
$echo "print this result" $(egrep -v -e '^(END|START)' file) " let see"

print this result let see I am after you
You are telling script that not to print line with END or START so you are getting only
print this result let see
