bash - Using sed to insert file content

Question

I'm trying to insert a file content before a given pattern

Here is my code:

sed -i "" "/pattern/ {
i\ 
r $scriptPath/adapters/default/permissions.xml"
}" "$manifestFile"

It adds the path instead of the content of the file.

Any ideas ?

In order to insert text before a pattern, you need to swap the pattern space into the hold space before reading in the file. For example:

sed "/pattern/ {
         h
         r $scriptPath/adapters/default/permissions.xml
         g
         N
     }" "$manifestFile"
