94 \fIblank\fRs. The first \fIword\fR specifies the name of the command to be
96 arguments to the invoked command. The command name is passed as argument 0 (see
97 \fBexec\fR(2)). The \fIvalue\fR of a \fIsimple-command\fR is its exit status if
102 A \fIpipeline\fR is a sequence of one or more \fIcommand\fRs separated by
103 \fB|\fR. The standard output of each \fIcommand\fR but the last is connected by
104 a \fBpipe\fR(2) to the standard input of the next \fIcommand\fR. Each
105 \fIcommand\fR is run as a separate process. The shell waits for the last
106 \fIcommand\fR to terminate. The exit status of a \fIpipeline\fR is the exit
107 status of the last command in the \fIpipeline\fR.
125 A \fIcommand\fR is either a \fIsimple-command\fR or one of the following.
126 Unless otherwise stated, the value returned by a command is that of the last
