read - Read from a file
read ?-nonewline? fileId
read fileId numBytes
In the first form, all of the remaining bytes are read from the file
given by fileId; they are returned as the result of the command.
If the -nonewline 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
numBytes bytes left in the file; in this case, all the remaining
bytes are returned.
FileId must be stdin or the return
value from a previous call to open; it must
refer to a file that was opened for reading.
Any existing end-of-file or error condition on the file is cleared at
the beginning of the read command.
