How to append text to a file in golang? [duplicate]

Question

I find os.Open() return a O_RDONLY file and os.Create() return a O_RDWR but can't find a method return a APPEND file pointer.

Any help ?

Answer 1

The OpenFile takes a flags argument that you can use:

 os.OpenFile("foo.txt", os.O_RDWR|os.O_APPEND, 0660);

Used with O_CREATE , OpenFile can also serve the same purpose as os.Create()
