  1. Use code tags around your code.
  2. Don't redirect your sed output before you get the right result.
  3. Try one sed expressions a time. Test
sed 's/something/another thing/' INPUTFILE

at first, then add another "s" command:

sed 's/.../.../ ; s/.../.../' INPUTFILE
3

first statement : sed -e s/\"\$hi/\$hi/ \ working fine replacing the patten in test.out file .
but in second one : test.res file contain space between " and / and i want to replace it to space and / ....please help

It will work. Just try and then learn about ordinary and double quotes in shell.
