i just want to substitude the multiple pattenm, i mean two to three word simulteneously. i.e
linux==LINUX
UNIX==unics
kernel==core
i need this replacement in vi editor .

as we do :s/linux/LINUX/g
this is for only one pattern .similarly i need all three in one.It's great if you put the knowdge in vi editor.

Maybe you really want to use sed:

cat file1 | sed -e '1,$s/linux/LINUX/g' | \
sed -e '1,$s/kernel/core/g' >file2

vi is designed to give you quick visual feedback.

If you want to do programmatic large scale substitutions, try sed, awk, or perl.

yha , i need what u did here. but u had done in two substitution in the solution . but i need to do such many substitution in lot of time so it's not benificial for me .

e.g i want to convert some of character in the file from capital to small letter. so what method you had mention is not give the complete solution .

I'll second Jerre. You might look into writing a short sed script that you can modify as needed.

grymoire.com has some excellent tutorials, including one on sed.
