shell scripting problems

[Tim Judd]

I'm sure it's faulty

Which is why I'm asking for help

My regexes (in it's various forms) produce the output similar to:
  xorg-fonts-75dpi
  xorg-fonts
  xorg-fonts-100dpi
  ...
  ...
  ...

and I'm wanting my regex to return the 2nd value, in this example, in this
list.

The problem is the shell is taking the end anchor $ as the start of a
variable, and no matter how I escape it, it seems to never work.

I'm sorry for not explaining properly.  Maybe the above would help.
