login shell is the shell a user uses when she logs in as
specified in passwd file. normal shell can be started any
time.

And, they read different rc files when startup.
Refer to the manual.

login shell and the normal shell are almost the same.
On most systems, they use the same command executable.
If sh/csh/tcsh were run as the login shell, they would
modify their process name in memory to -sh/-csh/-tcsh.

The '-' of the process names of shells are not added by
themselves. They are given by the process who invoked
shells, indicating that they should act as login shell.
This effect can also be enabled by command-line options,
-login for bash, or -l for tcsh.
