Missing argument to exec

Problem

I run a find command at the Fish shell and get this error:

$ find . -type f -exec sed -i 's/foo/bar/g' {} +
find: missing argument to `-exec`

Solution

This command has nothing wrong with it, it works under Bash. Fish expands the curly braces by default. So, for this to work, just enclose the curly braces in single quotes, so that it is not expanded. More details here.

Tried with: Fish 2.2.0 and Ubuntu 14.04
