tee [-i][-a

EXTERNAL INFLUENCES
Environment Variables
LC_MESSAGES determines the language in which messages are displayed.
If
LC_MESSAGES is not specified in the environment or is set to the empty string, the value of
LANG is
used as a default for each unspecified or empty variable. If
LANG is not specified or is set to the empty
string, a default of "C" (see lang(5)) is used instead of
LANG.
If any internationalization variable contains an invalid setting,
tee behaves as if all internationalization
variables are set to "C". See environ (5).
International Code Set Support
Single- and multibyte character code sets are supported.
RETURN VALUE
The
tee command returns zero upon successful completion, or nonzero if the command fails.
EXAMPLES
