-
-.SH DESCRIPTION
-.LP
-The \fBegrep\fR (\fIexpression grep\fR) utility searches files for a pattern of
-characters and prints all lines that contain that pattern. \fBegrep\fR uses
-full regular expressions (expressions that have string values that use the full
-set of alphanumeric and special characters) to match the patterns. It uses a
-fast deterministic algorithm that sometimes needs exponential space.
-.sp
-.LP
-If no files are specified, \fBegrep\fR assumes standard input. Normally, each
-line found is copied to the standard output. The file name is printed before
-each line found if there is more than one input file.
-.LP
-The \fBegrep\fR utility accepts the same form of full regular expressions as
-\fBgrep\fR(1) -E option.
-.sp
-.LP
-Be careful using the characters \fB$\fR, \fB*\fR, \fB[\fR, \fB^\fR, |, \fB(\fR,
-\fB)\fR, and \fB\e\fR in \fIfull regular expression\fR, because they are also
-meaningful to the shell. It is safest to enclose the entire \fIfull regular
-expression\fR in single quotes (\fBa\'\fR\fBa\'\fR).
-.sp
-.LP
-The order of precedence of operators is \fB[\|]\fR, then \fB*\|?\|+\fR, then
-concatenation, then | and NEWLINE.

-.SH DESCRIPTION
-.LP
-The \fBfgrep\fR (fast \fBgrep\fR) utility searches files for a character string
-and prints all lines that contain that string. \fBfgrep\fR is different from

-.LP
-The characters \fB$\fR, \fB*\fR, \fB[\fR, \fB^\fR, |, \fB(\fR, \fB)\fR, and
-\fB\e\fR are interpreted literally by \fBfgrep\fR, that is, \fBfgrep\fR does
-not recognize full regular expressions as does \fBegrep\fR. These characters
-have special meaning to the shell. Therefore, to be safe, enclose the entire
-\fIstring\fR within single quotes (\fBa\'\fR).

-.SH NOTES
-.LP
-Ideally, there should be only one \fBgrep\fR command, but there is not a single
-algorithm that spans a wide enough range of space-time tradeoffs.
-.sp
-.LP
-Lines are limited only by the size of the available virtual memory.
-.LP
-The \fB/usr/bin/fgrep\fR utility is identical to \fB/usr/bin/grep\fR
-\fB-F\fR (see \fBgrep\fR(1)). Portable applications should use
-\fB/usr/bin/grep\fR \fB-F\fR.
-.LP
-In the past the behavior of \fB/usr/xpg4/bin/fgrep\fR and
-\fB/usr/bin/fgrep\fR utilities was different. Now \fB/usr/bin/fgrep\fR
-is replaced by \fB/usr/xpg4/bin/fgrep\fR.

-Be careful using the characters \fB$\fR, \fB*\fR, \fB[\fR, \fB^\fR, \fB|\fR,
-\fB(\fR, \fB)\fR, and \fB\e\fR in the \fIpattern_list\fR because they are also

-.LP
-If no files are specified, \fBgrep\fR assumes standard input. Normally, each
-line found is copied to standard output. The file name is printed before each
-line found if there is more than one input file.
-.LP
-The options \fB-E\fR and \fB-F\fR affect the way \fBgrep\fR
-interprets \fIpattern_list\fR. If \fB-E\fR is specified,
-\fBgrep\fR interprets \fIpattern_list\fR as a full regular
-expression (see \fB-E\fR for description).  If \fB-F\fR is specified,
-\fBgrep\fR interprets \fIpattern_list\fR as a fixed string. If neither are
-specified, \fBgrep\fR interprets \fIpattern_list\fR as a basic regular
-expression as described on \fBregex\fR(5) manual page.

-.RE
-
-.SH USAGE
-.LP
-The \fB-e\fR \fIpattern_list\fR option has the same effect as the
-\fIpattern_list\fR operand, but is useful when \fIpattern_list\fR begins with
-the hyphen delimiter. It is also useful when it is more convenient to provide
-multiple patterns as separate arguments.
-.sp
-.LP
-Multiple \fB-e\fR and \fB-f\fR options are accepted and \fBgrep\fR uses all of
-the patterns it is given while matching input text lines. Notice that the order
-of evaluation is not specified. If an implementation finds a null string as a
-pattern, it is allowed to use that pattern first, matching every line, and
-effectively ignore any other patterns.
-.sp
-.LP
-The \fB-q\fR option provides a means of easily determining whether or not a
-pattern (or string) exists in a group of files. When searching several files,
-it provides a performance improvement (because it can quit as soon as it finds
-the first match) and requires less care by the user in choosing the set of
-files to supply as arguments (because it exits zero if it finds a match even if
-\fBgrep\fR detected an access or read error on earlier file operands).
-.SS "Large File Behavior"

-In the past the behavior of \fB/usr/xpg4/bin/grep\fR and
-\fB/usr/bin/grep\fR utilities was different. Now \fB/usr/bin/grep\fR
-is replaced by \fB/usr/xpg4/bin/grep\fR.

+In the past
+.Pa /usr/bin/grep ,
+.Pa /usr/bin/egrep ,
+and
+.Pa /usr/bin/fgrep
+were separate implementations, and were not standard conforming, with standard

+.Pa /usr/xpg4/bin/egrep ,
+and
+.Pa /usr/xpg4/bin/fgrep ,

+Now all non-conforming implementations are removed, and the ones previously
