Re: Set variable to shell command output

just wondering:  would you still want to do that if you knew vim
supports its own strftime function?

   :let td = strftime("%Y-%b-%d")

will give you a nice 11 character string in 'td', and you can
adjust to your preferences

I didn't know about that function, though I was interested in general solution as well.

As sc wrote, strftime() is a better solution in this case.  However,
for commands for which Vim does not have an internal equivalent, use
system(), e.g.,

   let stamp = system("date +%s")

That will include the trailing newline in your stamp variable.  If
that's undesirable, use this instead:

   let stamp = substitute(system("date +%s"), '\n', '', '')

This is it.

Thank you all a lot!
