 .Ss Lexical Structure
 The shell reads input in terms of lines from a file and breaks it up into
 words at whitespace (blanks and tabs), and at certain sequences of
 characters that are special to the shell called
 .Dq operators .
 There are two types of operators: control operators and redirection
 operators (their meaning is discussed later).
 The following is a list of operators:
 .Bl -ohang -offset indent
 .It "Control operators:"
-.Dl &  &&  \&(  \&)  \&;  ;; ;& | || <newline>
+.Dl &  &&  \&(  \&)  \&;  ;; ;& \&| || <newline>
 .It "Redirection operators:"
 .Dl <  >  >|  <<  >>  <&  >&  <<-  <>

 .Ss Quoting
 Quoting is used to remove the special meaning of certain characters or
 words to the shell, such as operators, whitespace, or keywords.
 There are four types of quoting:
 matched single quotes,
 matched double quotes,
 backslash,
 and
 dollar preceding matched single quotes (enhanced C style strings.)

 The standard output of all but

 The standard output of the last

 as is the standard input of the first command.

 The format for a pipeline is:
 .Pp
-.Dl [!] command1 [ | command2 ...]
+.Dl [!] command1 [ \&| command2 ...]
 .Pp
 The standard output of command1 is connected to the standard input of
 command2.
 The standard input, standard output, or both of each command is
 considered to be assigned by the pipeline before any redirection specified
 by redirection operators that are part of the command are performed.
 .Pp
 If the pipeline is not in the background (discussed later), the shell
 waits for all commands to complete.

 The commands in a pipeline can either be simple commands,
 or one of the compound commands described below.
 The simplest case of a pipeline is a single simple command.

 .Pp
 If the reserved word ! precedes the pipeline, the exit status
 becomes the logical NOT of the pipeline status as determined above.
 That is, if the pipeline status is zero, the exit status is 1;
 if the pipeline status is other than zero, the exit status is zero.
 If there is no ! reserved word, the pipeline status becomes the exit status.
 .Pp
 Because pipeline assignment of standard input or standard output or both
 takes place before redirection, it can be modified by redirection.
 For example:
 .Pp
-.Dl $ command1 2>&1 | command2
+.Dl $ command1 2>&1 \&| command2
 .Pp
 sends both the standard output and standard error of command1
 to the standard input of command2.

 Note that unlike some other shells, each process in the pipeline is a
 child of the invoking shell (unless it is a shell built-in, in which case
 it executes in the current shell -- but any effect it has on the
 environment is wiped).
