Good idea!  If you use csh or tcsh, add the lines:

    echo "alias g.man g.manual" >> $cshrc
    echo "alias g.rm g.remove" >> $cshrc
    echo "alias g.cp g.copy" >> $cshrc

to the file $GISBASE/etc/GIS.sh in the csh|tcsh alternative to the case
"$sh" statement.  Is that clear as mud?  Here's what I mean:

case "$sh" in

csh|tcsh)
    HOME=$LOCATION
    export HOME
    cshrc=$HOME/.cshrc
    tcshrc=$HOME/.tcshrc
    rm -f $cshrc $tcshrc
    echo "set home = $home" > $cshrc
    echo "set history = 30 noclobber ignoreeof" >> $cshrc

    echo "set prompt = '\\" >> $cshrc
    echo "Mapset <${MAPSET}> in Location <${LOCATION_NAME}> \\" >>
    $cshrc
    echo "GRASS 4.1 > '" >> $cshrc
    echo 'set BOGUS=``;unset BOGUS' >> $cshrc

    if [ -r $home/.grass.cshrc ]
    then
	cat $home/.grass.cshrc >> $cshrc
    fi

    if [ -r $home/.cshrc ]
    then
	grep '^ *set  *mail *= *' $home/.cshrc >> $cshrc
    fi

    if [ -r $home/.tcshrc ]
    then
	grep '^ *set  *mail *= *' $home/.tcshrc >> $cshrc
    fi

    if [ -r $home/.login ]
    then
	grep '^ *set  *mail *= *' $home/.login >> $cshrc
    fi

    echo "set path = ( $PATH ) " | sed 's/:/ /'g >> $cshrc

	This will give you g.man, g.cp, and g.rm, though the options
	still do not adhere to unix conventions.  You _could_ write
	shell scripts instead of simply using aliases and pass their
	arguments according to unix conventions without too much
	difficulty.  Needless to say, you need write permission in
	$GISBASE/etc/GIS.sh in order to add the lines above.
	Of course, if you use some other shell, you'll have to modify
	the command accordingly.
