If you're trying to compute the current date into a date-stamped filename, why not something like this:
Code:
#! /bin/ksh
filename=$(date +%b%e)
print -- ${filename/ /}.txt

In ksh (Korn Shell), and bash as well, you can set the variable "filename" to the date command (see man date for more formatting options). When I just tested it, I had a space in-between "Mar" and "1". So when I use the variable "$filename", I place it in curly braces, and add "/ /" - this tells my shell to echo the variable contents out, substituting the space with nothing, essentially removing it.

To be honest, I don't know if this will work with /bin/sh, or even with Posix shell, but it works with ksh and bash, as far as I know.

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
