[Bug 1047324] Re: dash globbing fails to obey ^

[D J Gardner]

Followup to my own bug... we all know globbing is not regex, but it seems posix globbing uses [!ab] not [^ab].
I've been using unix for over 20 years, and its the first time I've heard that. Oh well.

Title:
  dash globbing fails to obey ^

Status in “dash” package in Ubuntu:
  Invalid

Bug description:
  Versions known to be affected: 0.5.5.1-3ubuntu2 (lucid)
  0.5.7-2ubuntu2 (

  In every sane shell I've ever met the glob "[^ab]*" matches everything
  except files beginning with a or b.

  Current versions of dash ignore the ^ 
  (also foo[^~]  only matches foo~) 

  For systems that have dash as /bin/sh this breaks every shell script, makefile, etc. that makes use of 
  such inverse sets, possibly resulting in destruction of important files. e.g. 
  tar -czvf ../foo.tgz *[^~] will  only get the unwanted files.


  Demonstration code:
  $ mkdir oops ; cd oops ; touch afile bfile cfile ; dash -c 'echo [ab]*' ; dash -c 'echo [^ab]*' ;ls ;  cd ..
  afile bfile
  afile bfile
  afile  bfile  cfile
