vim automatically executes the replacement command every time
Every time you use vim to edit a file, a command similar to :1s/^./g/ will be automatically executed to automatically replace the first word of the first line.
Press http://vim.wikia.com/wiki/Troubleshooting and it’s still the same.
This problem will not occur if you use vi.
