the desired fields. During parsing, appropriate error messages will be
produced if there are format errors in any of the messages.

To override the output format used by
.BR scan ,
switches are used. This permits individual fields of
the scan listing to be extracted with ease. The string is simply a format
string and the file is simply a format file. See
-.BR mh\-format (5)
+.IR mh\-format (5)
for the details.

In addition to the standard
-.BR mh\-format (5)
+.IR mh\-format (5)
escapes,
.B scan
also recognizes the following additional

.SH HISTORY
Prior to using the format string mechanism,
.B \-header
used to generate
a heading saying what each column in the listing was. Format strings
prevent this from happening.
-
.SH BUGS
-The argument to the
-.B \-format
-switch must be interpreted as a single
-token by the shell that invokes
-.BR scan .
-Therefore, one must usually
-place the argument to this switch inside quotes.
