Replace 'foo' with 'bar' on lines 6 to 28 for the first occurrence of 'foo' in each line:

:6,28s/foo/bar
#Vim #MasteringVim #Programming

Come on after #FunFactory releasing the `#VIM`, which I needed because of the editor (yes I own the #MasteringVim books) #SlubbStore now released a wand attachment too... And I have been thinking about getting a #Slubb for months now ...

Oh man#FunFactory bringt jetzt einen Magic-Wand namens "VIM" auf den Markt

Als #Vim User muss ich den einfach holen

#MasteringVim gets an entirely different meaning in that context ^^
