I know I can start vim with a command by executing vim +"MyCommand", but if MyCommand takes a parameter it would be nice to start vim, as if I already typed :MyCommand but not actually executing it, so I can pass the argument with vim open, rather than from the command line (use case would be a trivial alias in bash). I tried vim +"normal :MyCommand" but that doesn't work it seems.

You can use feedkeys():

vim +'call feedkeys(":MyCommand")'

  • @Quasímodo How is that possible? It feels like you would need to have : somehow overridden in the vimrc for this NOT to work? Also as a ps.: making an alias with this is not trivial because of the amount of quotes, so ended up making a function.

  • There is an argument to feedkeys to prevent mappings from expanding. Re: the shell, yes, a function of script should be much easier to work with.
