Job Control

[Nikolas Britton]

Lets say I put a job in the background and then exit the shell (csh) and 
then open another shell, how do I get that background possess back into 
the foreground in the new shell?


Also:

%ll
drwxr-xr-x   2 nbritton  nbritton  -  512 Nov 22 04:40 test/
-rw-r--r--       1 nbritton  nbritton  -      0 Nov 22 04:40 test.tgz
%cd t*
t*: Ambiguous.
%cd test.tgz
test.tgz: Not a directory.
%

So whens is it possible to cd into a file or is cd really that stupid?
