For instance:

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?

chsh(1) General Commands Manual chsh(1)
NAME
chsh - change default login shell
SYNOPSIS
login-name [shell]
login-name [shell]
login-name [shell]
login-name [shell]
DESCRIPTION
The command changes the login-shell for a user's login name in the repository (see passwd(1)).
The DCE repository is only available if Integrated Login has been configured; see auth.adm(1M). If Integrated Login has been configured,
other considerations apply. A user with appropriate DCE privileges is capable of modifying a user's shell; this is not dependent upon
superuser privileges.
If the repository is not specified (as in [login-name]), the login shell is changed in the file only.
Run after running to make sure the information was processed correctly.
Notes
The command is a hard link to the command. When is executed, actually the command gets executed with appropriate arguments to change the
user login shell in the repository specified in command line. If no repository is specified, the login shell is changed in the file.
Arguments
login-name A login name of a user.
shell The absolute path name of a shell. If the file exists, the new login shell must be listed in that file. Otherwise, you
can specify one of the standard shells listed in the getusershell(3C) manual entry. If shell is omitted, it defaults to
the POSIX shell,
Options
The following option is recognized:
Specify the repository to which the operation is to be applied.
Supported repositories include and
Security Restrictions
You must have appropriate privileges to use the optional login-name argument to change another user's login shell.
NETWORKING FEATURES
NFS
File can be implemented as a Network Information Service (NIS) database.
EXAMPLES
To change the login shell for user to the default:
To change the login shell for user to the C shell:
To change the login shell for user to the Korn shell in the DCE registry:
WARNINGS
If two or more users try to write the file at the same time, a passwd locking mechanism was devised. If this locking fails after subse-
quent retrying, terminates.
