How to remove postfix from a string in bash?

Question

I want to to this in shell-script: remove the file postfix and save it into another variable:

file=abcabc.cpp
postf=.cpp
name=${file##postf}
echo $name

But this couldn't work. I want name=abcabc after the operation. Can you help me?

You can use:

name="${file%$postf}"
echo "$name"
abcabc
