@RudiC: if you use plain ls and filter within awk for *.txt then your suggestion will not be susceptible to maximum line length.

pfconfig
pfconfig(8c) pfconfig(8c)
Name
pfconfig - configure packet filter parameters
Syntax
/usr/etc/pfconfig [ +/-p[romisc] ] [ +/-c[opyall] ] [ -b[acklog] nnn ] [ -a[ll] ] [interface-name ...]
Description
The command allows the system manager to configure certain parameters of the packet filter driver (see These parameters are configured sep-
arately for each interface; the interfaces are specified by name on the command line (for example, and If more than one interface is speci-
fied, they are all given the same settings. Alternatively, you can specify -all to configure all the packet-filter interfaces on the sys-
tem.
You can set the following parameters with
+promisc Allows packet filter users to set the interface into promiscuous mode (receives all packets). Whenever there is at least one
packet filter descriptor open with the ENPROMISC mode bit set, the interface is put into promiscuous mode. When no such descrip-
tors are in use, the interface is returned to normal mode.
-promisc The interface is no longer put into promiscuous mode on behalf of packet filter users; if the interface is in promiscuous mode
when this command is given, it is returned to normal mode. (The superuser may use to control promiscuous mode, overriding the
mode set by non-superusers. This is the default setting.)
+copyall Allows packet filter users to set the interface into copy-all mode (receives packets sent/received by the kernel-resident proto-
col software [for example, IP, ARP, DECnet, LAT] on this host). Whenever there is at least one packet filter descriptor open
with the ENCOPYALL mode bit set, the interface is put into copy-all mode. When no such descriptors are in use, the interface is
returned to normal mode.
-copyall The interface is no longer put into copy-all mode on behalf of packet filter users; if the interface is in copy-all mode when
this command is given, it is returned to normal mode. (The superuser may use to control copy-all mode, overriding the mode set
by non-superusers. This is the default setting.)
-backlog nnn
Sets the maximum backlog (packet filter input queue length) for non-superuser descriptors to the specified number. When a
descriptor is opened, it is given a queue length limit of two. An application can increase this backlog using the EIOCSETW ioctl
request. Superusers are allowed to increase their backlog up to a system-wide maximum; non-superusers are allowed to increase
their backlog only up to the maximum set by this program. Note that allowing too large a backlog may result in vast amounts of
kernel memory being tied up in the packet filter driver queues.
If no configuration parameters are specified, the command displays the current packet filter configuration for the network interface(s).
Only the superuser may use this command to change the configuration.
Examples
On a system used for network monitoring, one might put this line into
/usr/etc/pfconfig -a +promisc -backlog 64
This allows users to run promiscuous network monitoring applications, with a maximum input queue length per application of 64 packets, on
any interface in the system.
/usr/etc/pfconfig -a +promisc +copyall -backlog 64
This allows promiscuous network monitoring applications to monitor communications to or from the local host, as well as the rest of the
local network.
Diagnostics
Messages indicating the specified interface do not exist; an attempt to set a maximum backlog less than 1 or greater than the system-wide
maximum; the user tried to alter an interface's configuration but is not privileged.
