.SH ENVIRONMENT
The environment variable
.SH "ENVIRONMENT VARIABLES"
.TP
.B GREP_OPTIONS
can hold a set of default
options for
.I grep.
These options are interpreted first and can be overwritten by explicit command
line parameters.
This variable specifies default options to be placed in front of any
explicit options. For example, if
.B GREP_OPTIONS
is
.BR "'\-\^\-binary-files=without-match \-\^\-directories=skip'" ,
.B grep
behaves as if the two options
.B \-\^\-binary-files=without-match
and
.B \-\^\-directories=skip
had been specified before any explicit options.
Option specifications are separated by whitespace.
A backslash escapes the next character,
so it can be used to specify an option containing whitespace or a backslash.
.TP
\fBLC_ALL\fP, \fBLC_MESSAGES\fP, \fBLANG\fP
These variables specify the
.B LC_MESSAGES
locale, which determines the language that
.B grep
uses for messages.
The locale is determined by the first of these variables that is set.
American English is used if none of these environment variables are set,
or if the message catalog is not installed, or if
.B grep
was not compiled with national language support (\s-1NLS\s0).
.TP
\fBLC_ALL\fP, \fBLC_CTYPE\fP, \fBLANG\fP
These variables specify the
.B LC_CTYPE
locale, which determines the type of characters, e.g., which
characters are whitespace.
The locale is determined by the first of these variables that is set.
The \s-1POSIX\s0 locale is used if none of these environment variables
are set, or if the locale catalog is not installed, or if
.B grep
was not compiled with national language support (\s-1NLS\s0).
.TP
.B POSIXLY_CORRECT
If set,
.B grep
behaves as \s-1POSIX.2\s0 requires; otherwise,
.B grep
behaves more like other \s-1GNU\s0 programs.
\s-1POSIX.2\s0 requires that options that follow file names must be
treated as file names; by default, such options are permuted to the
front of the operand list and are treated as options.
Also, \s-1POSIX.2\s0 requires that unrecognized options be diagnosed as
\*(lqillegal\*(rq, but since they are not really against the law the default
is to diagnose them as \*(lqinvalid\*(rq.
.B POSIXLY_CORRECT
also disables \fB_\fP\fIN\fP\fB_GNU_nonoption_argv_flags_\fP,
described below.
.TP
\fB_\fP\fIN\fP\fB_GNU_nonoption_argv_flags_\fP
(Here
.I N
is
.BR grep 's
numeric process ID.) If the
.IR i th
character of this environment variable's value is
.BR 1 ,
do not consider the
.IR i th
operand of
.B grep
to be an option, even if it appears to be one.
A shell can put this variable in the environment for each command it runs,
specifying which operands are the results of file name wildcard
expansion and therefore should not be treated as options.
This behavior is available only with the \s-1GNU\s0 C library, and only
when
.B POSIXLY_CORRECT
is not set.
