I've long set my most-recently visited directories to shell variables d1, d2, etc.
On an ancient Fedora machine I could type a command like
$ cp $d1/
and the shell would replace $d1 with text like /home/acctname/projects/blog/ and would then show me the contents of .../blog, like you would expect any tab-completion to do.
Now, both ubuntu wheezy/sid and fedora 16 just \-escape the '$', and naturally there are no completions to show.
You can see this behavior in action in an OSX Terminal window. On 10.8, do something like
ls $HOME/ to see what I mean.
Is there a bash shell variable or option that can restore the old behavior?
man bash suggests this is a bug:
complete (TAB) Attempt to perform completion on the text before point. Bash attempts completion treating the text as a variable (if the text begins with $), username (if the text begins with ~), hostname (if the text begins with @), or command (including aliases and functions) in turn. If none of these produces a match, filename completion is attempted.
I get the above described completion when a token starts with '~' or a letter. It's just '$'-completion that's broken.
