Solution
Copy the files from /usr/dt/config/*/Xresources to /etc/dt/config/*/Xresources and add the Dtlogin*greeting.labelString and Dtlogin*greeting.persLabelString parameters to all copied Xresources files: for file in /usr/dt/config/*/Xresources; do dir='dirname $file | sed s/usr/etc/' mkdir -p $dir if [ ! -f $dir/Xresources ]; then cp $file $dir/Xresources fi WARN='Authorized uses only. All activity may be monitored and reported.' echo 'Dtlogin*greeting.labelString: $WARN' >> $dir/Xresources echo 'Dtlogin*greeting.persLabelString: $WARN' >> $dir/Xresources done Default Value: N/A
