To do what you want you would need to embed your password in a script in plain text - not good for security! Do you really want to do this?

did a big mistake, changing root entry of /etc/passwd to
root:x:0:0:root:/root:/usr/bin/tmux split-window -v \; attach
as expected, now I can't login as root anymore. sudo ed /etc/passwd etc. doesn't work.
Any idea?

vncpasswd
vncpasswd(1) Virtual Network Computing vncpasswd(1)
NAME
vncpasswd - change the VNC password
SYNOPSIS
vncpasswd [passwd-file]
vncpasswd -f
DESCRIPTION
vncpasswd allows you to set the password used to access VNC desktops. Its default behavior is to prompt for a VNC password and then store
an obfuscated version of this password to passwd-file (or to $HOME/.vnc/passwd if no password file is specified.) The vncserver script
runs vncpasswd the first time you start a VNC desktop, and it invokes Xvnc with the appropriate -rfbauth option. vncviewer can also be
given a password file to use via the -passwd option.
The password must be at least six characters long (unless the -f command-line option is used-- see below), and only the first eight charac-
ters are significant. Note that the stored password is not encrypted securely - anyone who has access to this file can trivially find out
the plain-text password, so vncpasswd always sets appropriate permissions (read and write only by the owner.) However, when accessing a
VNC desktop, a challenge-response mechanism is used over the wire making it hard for anyone to crack the password simply by snooping on the
network.
OPTIONS
-f Filter mode. Read a plain-text password from stdin and write an encrypted version to stdout. Note that in filter mode, short or
even empty passwords will be silently accepted.
FILES
$HOME/.vnc/passwd
Default location of the VNC password file.
