What shell is this? You may be able to use more graceful, safe, and simple things than eval in shells better than a generic bourne.

chsh(1) General Commands Manual chsh(1)
NAME
chsh - change login shell
SYNOPSIS
chsh [-D binddn] [-P path] [-s shell] [-l] [-q] [-u] [-v] [user]
DESCRIPTION
chsh is used to change the user login shell. A normal user may only change the login shell for their own account, the super user may
change the login shell for any account.
If a shell is not given on the command line, chsh operates in an interactive fashion, prompting the user with the current login shell.
Enter the new value to change the field, or leave the line blank to use the current value. Enter none to remove the current value. The
current value is displayed between a pair of [ ] marks.
The only restrictions placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker is the super-
user, and then any value may be added. An account with a restricted login shell may not change their login shell.
This version of chsh is able to change the shell of local, NIS, NIS+ and LDAP accounts , if the permissions allow it.
OPTIONS
-D, --binddn binddn
Use the Distinguished Name binddn to bind to the LDAP directory. The user will be prompted for a password for simple authentica-
tion.
-P, --path path
The passwd file is located below the specified directory path. chsh will use this files, not /etc/passwd. This is useful for exam-
ple on NIS master servers, where you do not want to give all users in the NIS database automatic access to your NIS server and the
NIS map is build from special files.
-s, --shell
Specify your login shell.
-l, --list-shells
Print the list of shells listed in /etc/shells and exit.
-q, --quite
Don't be verbose.
-u, --usage
Print a usage message and exit.
--help
Print a more verbose help text and exit.
-v, --version
Print version information and exit.
FILES
/etc/passwd - user account information
/etc/shells - list of valid login shells
