[X2Go-Dev] Bug#1609: Location of Dollar Sign

[Stefan Baur]

Hi Bart,

is that dollar sign located at the beginning, in the middle, or at the 
end of the user name?

man 8 useradd states (emphasis mine):

"It is usually recommended to only use usernames that begin with a lower 
case letter or an underscore, followed by lower case letters, digits, 
underscores, or dashes. They can *end* with a dollar sign. In regular 
expression terms: [a-z_][a-z0-9_-]*[$]?"

Kind Regards,
Stefan Baur
