I am using bufio to append byte arrays to a file. When I use cat on it I get:

So arrays of bytes. Now I want to read the file into memory, so I use:
content, err := ioutil.ReadFile(filename)
But when I display the content variable I get a completely different output than the contents of the file (and one array instead of many). What's wrong?
You wrote it wrong to the file. Its human readable format, should be binary.
My guess you used something like fmt.Fprintln(file, byte_slice) or variants.
It must be fmt.Fprintf(file, "%s", byte_slice) or similar.
Please, show us code how you write to the file.
So what think is happening is that the content inside of that file is a string. When you pull it out of the file it converts that string to bytes. What you need to do is convert those bytes to a string before you append to the file and then convert them back when you pull from the file
