I am sure this is written somewhere but can't get it to work.

echo `date +"<span size=\\"15\\"><b>%A, %-Y-%m-%-d - Vecka %W</b></span>"`

What am i doing wrong? Also i am trying to make a button to switch my kernel-setting to use limits. In this case i don't want the "root shell enabled" output. Just want the bg to show. Is it possible to get output not to show?
