FC_REMOTE_PORT_ADD(9) SCSI mid layer FC_REMOTE_PORT_ADD(9)NAME
fc_remote_port_add - notify fc transport of the existence of a remote FC port.
SYNOPSIS
struct fc_rport * fc_remote_port_add(struct Scsi_Host * shost, int channel, struct fc_rport_identifiers * ids);
ARGUMENTS
shost
scsi host the remote port is connected to.
channel
Channel on shost port connected to.
ids
The world wide names, fc address, and FC4 port roles for the remote port.
DESCRIPTION
The LLDD calls this routine to notify the transport of the existence of a remote port. The LLDD provides the unique identifiers (wwpn,wwn)
of the port, it's FC address (port_id), and the FC4 roles that are active for the port.
For ports that are FCP targets (aka scsi targets), the FC transport maintains consistent target id bindings on behalf of the LLDD. A
consistent target id binding is an assignment of a target id to a remote port identifier, which persists while the scsi host is attached.
The remote port can disappear, then later reappear, and it's target id assignment remains the same. This allows for shifts in FC addressing
(if binding by wwpn or wwnn) with no apparent changes to the scsi subsystem which is based on scsi host number and target id values.
Bindings are only valid during the attachment of the scsi host. If the host detaches, then later re-attaches, target id bindings may
change.
This routine is responsible for returning a remote port structure. The routine will search the list of remote ports it maintains internally
on behalf of consistent target id mappings. If found, the remote port structure will be reused. Otherwise, a new remote port structure will
be allocated.
Whenever a remote port is allocated, a new fc_remote_port class device is created.
Should not be called from interrupt context.
NOTES
This routine assumes no locks are held on entry.

I know through (my very limited) experience that you can't use the asterisk alone in a regex, but I still don't quite understand why. After all, it should match 'any or no characters'. To my mind, '*grep' should match:
grep
egrep
fgrep
While '.*grep' should match
egrep
fgrep

My original files are like this below and I distinguish them from the AP_ID (file1 has 572 and file2 has 544). Also, the header on file1 has “G_” pre-pended. NOTE: these are only snippets of very large files and much of the data is not present here.
