Setting the locale

Use the export command to set the locale.

The following command sequence:
LANG=C
export LANG

sets the default locale to C (that is, C is used unless a given variable, such as LC_COLLATE, is explicitly set to something else).

The following sequence:
LC_ALL=C
export LC_ALL

forcibly sets all the locale variables to C, regardless of previous settings.

For a report on the current settings of the locale variables, type locale.
