Is there a way to read a .vimrc file for only a single ssh session?  That is, when I log in I perform some operation so that vim uses say /tmp/myvimrc until I log out?I do not want to permanently overwrite the current .vimrc, I just need to use a different set of settings for the duration of my login every once in a while.
Temporary .vimrc
vim;configuration;vimrc
Suppose you have this other set of settings in /tmp/myvimrc.  If my reading of man vim is correct you can start vim with this set of settings using the following:$ vim -u /tmp/myvimrcThus, to make this an option for the rest of the session, I would create a function that sets this as an alias for vim.  Thus, in bash I would put something like this in my .bashrc file:function vimswitch {    alias vim='vim -u /tmp/myvimrc'}Then, when I wanted my new vim settings, I would just run:$ vimswitchNote that I wouldn't store myvimrc in /tmp since this could easily be cleared out upon reboot.  If you are using a shell other than bash this should still be possible, but the syntax could differ slightly.
