Hi,

I could not find a command to save all the buffers at once... could
anyone tell me how to do it?

Thanks a lot!

One easy way to save all unsaved buffers is this:

type Alt+x ibuffer, then type “* u” to mark all unsaved buffer, then
type “S” to save them all. Type “D” to close them all if you want.

I have wrote a little tutorial on ibuffer here if you are curious:
