When you use bash on ubuntu and press tab key for tab completion, you would got warning message like this:
“bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8)”
I googled for this problem, and got a solution from ubuntu forum.
Just adding the line in /etc/default/locale:
#———————–
LC_ALL=”en_US.UTF-8″
#———————–
Then the warning message never appear if you press tab key for completing file name or path.
