bashrc alias search and replace using sed

Question

I frequently need to search and replace throughout my code base. I use sed:

find . -type f -exec sed -i 's/foo/bar/g' {} +

I would like to be able to just type

sr 's/foo/bar/g'

I tried to add this to my .bashrc:

function sr
{
    find . -type f -exec sed -i '$1' {} +
}

But when I try to run sr 's/foo/bar/g'

I get

sed: -e expression #1, char 1: unknown command: `%'

How can I fix the above?

Answer 1

I found a solution:

function sr()
{
    find . -type f -exec sed -i "$1" {} +
}
