Bourne Shell: Hiding error messages

I am executing commands as follows in Bourne shell script. Filenames/directory names for the deletion/copying are unknown:

rm *
rmdir <directory>
cp -p * <directory>

Sometimes when no file or directory exists, error is encountered. This has no impact or whatever issue to my script but it's ugly to show to the users.

I want to prevent the error message from being displayed. Is there a way for me to prevent it?

NAME
resize - set TERMCAP and terminal settings to current xterm window size SYNOPSIS
resize [-u] [-c] [-s[row col]] OPTIONS
The following options may be used with resize: This option indicates that Bourne shell commands should be generated even if the user's cur- rent shell is not /bin/sh. This option indicates that C shell commands should be generated even if the user's current shell is not /bin/csh. This option indicates that Sun console escape sequences will be used instead of the special xterm escape code. If rows and col- umns are given, resize will ask the xterm to resize itself. However, the window manager may choose to disallow the change. DESCRIPTION
The resize command prints a shell command for setting the TERM and TERMCAP environment variables to indicate the current size of xterm win- dow from which the command is run. For this output to take effect, resize must either be evaluated as part of the command line (usually done with a shell alias or function) or else redirected to a file which can then be read in. From the C shell (usually known as /bin/csh), the following alias could be defined in the user's % alias rs 'set noglob; eval `resize`' After resizing the window, the user would type: % rs Users of versions of the Bourne shell (usually known as /bin/sh) that do not have command functions will need to send the output to a tem- porary file and the read it back in with the "." command: $ resize > /tmp/out $ . /tmp/out FILES
for the base termcap entry to modify. user's alias for the command. BUGS
The -u or -c must appear to the left of -s if both are specified. SEE ALSO
