[Bug 1073077] Re: zsh complains about locale_warn on launch

[Scott Moser]

It would seem to me that this is a bug in zsh.
It is demonstrable like this:

ubuntu at quantal$ sh -c 'f="foo=bar"; echo ${f%%=*}'
foo
ubuntu at quantal$ bash -c 'f="foo=bar"; echo ${f%%=*}'
foo
ubuntu at quantal$ zsh -c 'f="foo=bar"; echo ${f%%=*}'
zsh:1: * not found

It is work-aroundable by escaping the '=' in the shell suffix match with a '\'.  Ie:
zsh -c 'f="foo=bar"; echo ${f%%\=*}'
foo


** Also affects: zsh (Ubuntu)
   Importance: Undecided
       Status: New

** Description changed:

+ zsh complains if an '=' occurs in a suffix or prefix shell parameter
+ expansion.
+ 
+   $ sh -c 'f="foo=bar"; echo ${f%%=*}'
+   foo
+   $ bash -c 'f="foo=bar"; echo ${f%%=*}'
+   foo
+   $ zsh -c 'f="foo=bar"; echo ${f%%=*}'
+   zsh:1: * not found
+ 
+ It is work-aroundable by escaping the '=' in the shell suffix match with a '\'. Ie:
+   $ zsh -c 'f="foo=bar"; echo ${f%%\=*}'
+   foo
+ 
+ 
+ == original bug report ==
+ 
  After upgrading my Amazon machine to Ubuntu 12.04, every time I run zsh I get the following output:
-     locale_warn:13: * not found
+     locale_warn:13: * not found
  
  Apparenlty this is caused by the file /etc/profile.d/Z99-cloud-locale-
  test.sh in the cloud-init package. zsh always outputs an error when a
  glob like * fails to match any files.
