I've stripped all LC_* variables plus LANG from my environment: > $ env|fgrep LANG > $ env|fgrep LC_ > $
Command completion still used "EN_us" for sorting directories in command completion. e.g.: $ cd .adobe/ .gtkrc-1.2-gnome2 .profile .altera.quartus/ .hist/ .python-eggs/ .bash_history .hplip/ .qt/ .bashrc .ICEauthority .recently-used bin/ .icons/ .recently-used.xbel .com.oxygenxml/ info/ .redhat/ .config/ .install4j .reviewboardrc .cvspass .java/ SamaraSample/ .DCOPserver_bkorb-dt__0 .kde/ .sane/ .DCOPserver_bkorb-dt_:0 .kderc .Skype/ Desktop/ .lesshst .sopc_builder/ .dmrc .local/ .ssh/ Documents/ .macromedia/ .subversion/ Downloads/ man/ sw/ .eggcups/ .mcop/ tmp/ .emacs .merlot/ .Trash/ .emacs.d/ .metacity/ Videos/ .esd_auth Mod/ .viminfo .evolution/ .mozilla/ .VirtualBox/ .fontconfig/ .nautilus/ VirtualBoxImages/ .gconf/ new-dmgr/ work/ .gconfd/ nios2bin/ .Xauthority .gitconfig NVIDIA/ .xcompmgrrc .gnome/ .openoffice.org/ .Xdefaults .gnome2/ .openoffice.org2.0/ xsd-parse/ .gnome2_private/ .p4qt/ .xsession-errors .google/ .p4tickets yang-dm/ .gstreamer-0.10/ Pictures/ $ ls -A .DCOPserver_bkorb-dt_:0 .fontconfig .merlot .xsession-errors .DCOPserver_bkorb-dt__0 .gconf .metacity Desktop .ICEauthority .gconfd .mozilla Documents .Skype .gitconfig .nautilus Downloads .Trash .gnome .openoffice.org Mod .VirtualBox .gnome2 .openoffice.org2.0 NVIDIA .Xauthority .gnome2_private .p4qt Pictures .Xdefaults .google .p4tickets SamaraSample .adobe .gstreamer-0.10 .profile Videos .altera.quartus .gtkrc-1.2-gnome2 .python-eggs VirtualBoxImages .bash_history .hist .qt bin .bashrc .hplip .recently-used info .com.oxygenxml .icons .recently-used.xbel man .config .install4j .redhat new-dmgr .cvspass .java .reviewboardrc nios2bin .dmrc .kde .sane sw .eggcups .kderc .sopc_builder tmp .emacs .lesshst .ssh work .emacs.d .local .subversion xsd-parse .esd_auth .macromedia .viminfo yang-dm .evolution .mcop .xcompmgrrc So BASH must have squirreled away the setting before I removed it from the environment and used this Very Broken sorting order. (Who thought this was clever, I wonder. That's off topic.....)
