As part of a bigger task, I had to read thru a file and separate records into various batches based on a field. Specifically, separate records based on the value in the batch field as defined below. The batch field left-justified numbers.
The datafile is here
My script is here (and includes info on file layout)
This is all greatly simplified from my overall task which was then to perform data manipulations on the separated files. However, my small script above with the awk command merely creates 15 files that are empty.
So, what is wrong with the syntax?
Hi All,
I need to select only those records having a non zero record in the first column of a comma delimited file.

pvmfnotify
NOTIFY(3PVM) PVM Version 3.4 NOTIFY(3PVM)NAME
pvm_notify - Request notification of PVM event such as host failure.
SYNOPSIS
C int info = pvm_notify( int what, int msgtag, int cnt, int *tids )
Fortran call pvmfnotify( what, msgtag, cnt, tids, info )
PARAMETERS
what Type of event to trigger the notification. Presently one of:
Value Meaning
PvmTaskExit Task exits or is killed
PvmHostDelete Host is deleted or crashes
PvmHostAdd New host is added
msgtag Message tag to be used in notification.
cnt For PvmTaskExit and PvmHostDelete, specifies the length of the tids array. For PvmHostAdd, specifies the number of times to
notify.
tids For PvmTaskExit and PvmHostDelete, an array of length cnt of task or pvmd TIDs to be notified about. The array is not used with
the PvmHostAdd option.
info Integer status code returned by the routine. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_notify requests PVM to notify the caller on detecting certain events. One or more notify messages (see below) are sent by
PVM back to the calling task. The messages have tag msgtag supplied to notify.
The notification messages have the following format:
PvmTaskExit
One notify message for each TID requested. The message body contains a single TID of exited task.
PvmHostDelete
One notify message for each TID requested. The message body contains a single pvmd-TID of exited pvmd.
PvmHostAdd
cnt notify messages are sent, one each time the local pvmd's host table is updated. The message body contains an integer length
followed by a list of pvmd-TIDs of new pvmds. The counter of PvmHostAdd messages yet to be sent is replaced by successive calls to
pvm_notify. Specifying a cnt of -1 turns on PvmHostAdd messages until a future notify; a count of zero disables them.
TIDs in the notify messages are packed as integers.
The calling task is responsible for receiving messages with the specified tag and taking appropriate action.
Future versions of PVM may expand the list of available notification events.
EXAMPLES
C:
info = pvm_notify( PvmTaskExit, 9999, ntask, tids );
Fortran:
CALL PVMFNOTIFY( PVMHOSTDELETE, 1111, NUMHOSTS, DTIDS, INFO )
To "cancel" a notify request in PVM, the pvm_notify routine can be re-invoked with an additional PvmNotifyCancel flag in the what argument.
The remaining arguments to this cancelling invocation must match the original invocation exactly, aside from the additional PvmNotifyCancel
which can be added(+) or OR-ed(|) to the what argument:
pvm_notify( PvmTaskExit, 9999, ntask, tids );
. . .
pvm_notify( PvmTaskExit | PvmNotifyCancel, 9999, ntask, tids );
Note that when a notify is cancelled, the notify message is delivered, as if the given event (i.e. task exit, host add or delete) had
occurred.
ERRORS
PvmSysErr
pvmd not responding.
PvmBadParam
giving an invalid argument value.
