- .SH SYNOPSIS
- \fBread \fR?\fB\-nonewline\fR? \fIfileId\fR
- .br
- \fBread \fIfileId numBytes\fR
- .BE
-
- .SH DESCRIPTION
- .PP
- In the first form, all of the remaining bytes are read from the file
- given by \fIfileId\fR; they are returned as the result of the command.
- If the \fB\-nonewline\fR switch is specified then the last
- character of the file is discarded if it is a newline.
- In the second form, the extra argument specifies how many bytes to read;
- exactly this many bytes will be read and returned, unless there are fewer than
- \fInumBytes\fR bytes left in the file; in this case, all the remaining
- bytes are returned.
- \fIFileId\fR must be \fBstdin\fR or the return
- value from a previous call to \fBopen\fR; it must
- refer to a file that was opened for reading.

- .SH KEYWORDS
- file, read
