[Bug 1280336] [NEW] CoreUtils 8.13 /bin/ls "-1" (single column) parameter apparently positional

[Lumenary]

Public bug reported:

Hello,
 
 
 
On Ubuntu 12.04.3LTS (Precise Pangolin), using the stock "/bin/ls" (list directory) command, the location of the "-1" (a hyphen followed by the digit "one") parameter is apparently position dependent.
 
 
For example, this command generates unexpectedly incorrect output (leading periods used only for indentation purposes):
 
.. testuser at testhost:~/.unison$ ls -1 -x
.. Audiobooks.prf  Configuration.prf  default.prf  Documents.prf  Downloads.prf
.. Ebooks.prf      Emulation.prf      Music.prf    Pictures.prf   Podcasts.prf
.. Projects.prf    Templates.prf      Videos.prf
.. testuser at testhost:~/.unison$
 
(Spacing may not be accurately represented in a web browser; open attached text file in a text editor with a fixed-width font for an accurate example.)
 
 
While this command produces the correct output  (leading periods used only for indentation purposes):
 
.. testuser at testhost:~/.unison$ ls -x -1
.. Audiobooks.prf
.. Configuration.prf
.. default.prf
.. Documents.prf
.. Downloads.prf
.. Ebooks.prf
.. Emulation.prf
.. Music.prf
.. Pictures.prf
.. Podcasts.prf
.. Projects.prf
.. Templates.prf
.. Videos.prf
.. testuser at testhost:~/.unison$
 
(Spacing may not be accurately represented in a web browser; open attached text file in a text editor with a fixed-width font for an accurate example.)

 
This behaviour is unexpected and violates non-positional parameter guidelines.
