[TxMt] TM_USERNAME is null on Leopard

[Kai Janson]

Yes, I am running Leopard 10.5.1 and there is actually a white space  
in front of the name.
I assume that your dscl . -read /Users/$USER RealName |sed 's/ 
RealName: //' works on Tiger but it does not
work on Leopard.

There is no trailing white space on Leopard, thus it fails to sed  
anything.
The technique I use is overkill.  I could have used

	dscl . -read /Users/$USER RealName | tail -1

but then I would end up with the name plus a leading white space.

	dscl . -read /Users/$USER RealName | tail -1 | sed -e "s/^\ //"

That line fishes the real name out of dscl's database, then eliminates  
the first line altogether and finally removes the leading white space  
if there is one.

Here a snippet from my shell:

mac-mini-intel:Tasks kjanson$ res=`dscl . -read /Users/$USER RealName  
| tail -1`
mac-mini-intel:Tasks kjanson$ echo "'$res'"
' Kai Janson'
mac-mini-intel:Tasks kjanson$ res=`dscl . -read /Users/$USER RealName  
| tail -1 | sed -e "s/^\ //"`
mac-mini-intel:Tasks kjanson$ echo "'$res'"
'Kai Janson'
