Need some hacks.
Need a hack. Fine, it is simple. Write your own shell! Standard shells are required to accept user-defined variable names that contain the 52 uppercase and lowercase letters (a-z, A-Z), the 10 digits (0-9) and underscore (_). The shell is allowed to accept other characters in user-defined names, but is not required to do so. I have not seen any standards conforming shell that accepts a period (.) in a user-defined variable name.

CHSH(1) User Commands CHSH(1)
NAME
chsh - change your login shell
SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username]
DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one.
chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries.
OPTIONS
-s, --shell shell
Specify your login shell.
-l, --list-shells
Print the list of shells listed in /etc/shells and exit.
-u, --help
Print a usage message and exit.
-v, --version
Print version information and exit.
VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in
the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you
are root.
EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid.
SEE ALSO
login(1), passwd(5), shells(5)
AUTHOR
Salvatore Valente <svalente@mit.edu>
AVAILABILITY
The chsh command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
