FROM Command
The remainder of this subsection describes these commands in detail with a brief
description of each command, the command syntax, and any special considerations
applicable to the command.
For a description of the notation scheme used here, see Notation Conventions on
page -xxviii.
FROM Command
The FROM command causes the PTrace kernel to open the trace file and read the
device type and subtype information from the header. If a trace file is currently in use,
PTrace closes it before opening the new one.
file-name
is the name of a trace file.
The syntax of file-name is as follows:
where:
•
\system-name identifies a specific system within a network. For example, \NOVA.
•
$volume-name identifies a physical disk pack mounted on a disk unit. For
example, $DATA5.
•
subvolume-name identifies a related set of files defined by the user. For example,
SNMT101.
•
file-id identifies a particular file within the subvolume. For example,
ZZSMPTRP.
For convenience, default values are provided for all parts except file-id. The initial
default values are the values provided by the TACL or SCF process through which you
invoked PTrace. For example, if you invoke PTrace while your current system, volume,
and subvolume are \NOVA.$DATA5.SNMT101, then your default system, volume, and
subvolume are \NOVA.$DATA5.SNMT101.
NEXT Specifies the number of records or specifies a time after which records are to
be displayed or printed
RECORD Displays or prints record(s) within the specified range or prints all records
SELECT Establishes selection criteria for displaying records
FROM file-name
[\system-name.] [$volume-name.] [subvolume-name.] file-id
