Re: a little problem with the second argument to cd

[Dominik Vogt <dominik.vogt@xxxxxx>]

Well, I thought someone else might be interested in my cd
function:

0, 3 or more arguments:

  Works like "builtin cd"

1 Argument

  - If the argument is a directory name it cds into it.
  - If the name ends with a colon, and a directory with the colon
    stripped from the name exists, it cds into it.  (Usefull for
    cut-and-paste).
  - If the argument is a file and the file name ends in .tar.gz,
    .tar.bz2, .tgz, .TGZ, .zip or .ZIP, it strips the suffix and
    cds into the directory with that name (if there is one).
  - If the argument is a plain file, it cds into the directory in
    which the file resides.
  - If all the above attempts fail, works like "builtin cd $1".

2 Arguments

  As discussed above.

Ciao
