KB#00233-BBx chooses the incorrect alias line from the config.bbx file

Title:

BBx chooses the incorrect alias line from the config.bbx file

Description:

The order that the alias lines appear in the config.bbx file is very important. When BBx compares the tty device to the devices listed in the config.bbx file, it will take the first alias that has a partial match. Here's an example showing an alias order that can cause problems: 

alias T001 /dev/tty010 term 
alias T101 /dev/tty01 term 

If BBx is run from /dev/tty01, then it will take the first alias line rather than the second one (as is expected). 

Some Unix operating systems allow multiple device names off one device name, i.e., one parent and many children. The parent must be defined first: tty01; then the children can be defined: tty010; tty011; tty01, as in the following example aliases: 

alias T101 /dev/tty01 term 
alias T001 /dev/tty010 term 
alias T002 /dev/tty011 term 
alias T003 /dev/tty012 term
