If using sed:

Code:
sed -e '/^START/d' -e '/^END/d' < inputfile > outputfile

An awk Approach

Code:
$ awk '!/START/&&!/END/'  inputfile >outputfile

Thanks for your quick replay,
I got another issue.
I tried it in command line, it works
but if I put in script, it doesn't work.
below is the portition, it print out "here", but doesn't delete the line
Code:
else
echo "here"
sed -e '/^ALL/d' -e '/^FILE/d' < file> file_tmp
#mv file_tmp file

Thanks again.

You can also use grep

Code:
grep -v -E '^(END|START)'  infile >outfile

i got error.
Code:
grep -v -E '^(END|START)' infile

Code:
grep: illegal option -- E
Usage: grep -hblcnsviw pattern file . . .

My OS is
SunOS 5.10 Generic_144488-17 sun4v sparc SUNW,SPARC-Enterprise-

Thanks
