Go fmt on a whole source tree

Question

I have a project currently organized something like this:

~/code/go
         /bin
         /pkg
         /src
             /proj/main.go
                  /some_packa         


        

Answer 1

find proj -type f -iregex '.*\.go' -exec go fmt '{}' +

Explanation

• find proj: find everything in this directory...
  • -type f: ...that is a file
  • -iregex '.*\.go': ...and case-insensitively matches the regular expression .*\.go
• ...and execute go fmt followed by as many matched files as the operating system can handle passing to an executable in one go.
