6.4 Shell

Command: shell command

Command: defshell command

(none)
Set the command to be used to create a new shell. This overrides the value of the environment variable $SHELL. This is useful if you’d like to run a tty-enhancer which is expecting to execute the program specified in $SHELL. If the command begins with a ‘-’ character, the shell will be started as a login-shell. Typical shells do only minimal initialization when not started as a login-shell. E.g. Bash will not read your ~/.bashrc unless it is a login-shell.

defshell is currently a synonym to the shell .screenrc command.

Command: shelltitle title

(none)
Set the title for all shells created during startup or by the C-a C-c command. See Naming Windows, for details about what titles are.
