I use in Arch linux
sudo netstat -at | grep LISTEN
[sudo] password for pal:
tcp 0 0 0.0.0.0:ssh 0.0.0.0:* LISTEN
tcp6 0 0 [::]:ssh [::]:* LISTEN

in FreeBSD
>sudo netstat -at | grep LISTEN
Password:
netstat: illegal option -- t
How can I see listening ?

Also remember netstat(1) on the various Linux distros is deprecated. See https://www.redhat.com/en/blog/deprecated-linux-command-replacements.

netstat is a command-line tool used to display network connections, routing tables, interface statistics, and other network-related information. It's available on various operating systems like Windows, Linux, and macOS. You can use netstat to troubleshoot network issues, monitor connections, and analyze network traffic.

The netstat command in Ubuntu is used to display network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. It's a versatile tool for network diagnostics and troubleshooting. If you encounter a "bash: netstat: command not found" error, it means the net-tools package, which includes netstat, is not installed. (.deb)
netstat is a command-line utility used on Linux systems, including Rocky Linux, to display network connections, routing tables, interface statistics, and masquerade connections. While netstat is part of the older net-tools package and has been superseded by newer tools like ss and ip, it remains widely used and is still available for installation on modern distributions like Rocky Linux. (.rpm)
It turns out that netstat is missing only in red hat and not in most Linux.
Maybe Red Hat abandoned Netstat purely for commercial reasons, Red Hat is a paid system

Read this again, carefully.

No, it can still be installed separately, just like on Ubuntu, Rocky, and all the other Linux distributions. It's just not installed by default anymore.

Has nothing to do with it.

On Linux try ss(8) which is very much modelled after our sockstat(1).
Code: 
       -l, --listening
	      Display only listening sockets (these are	omitted	by default).

That's good to know. How do I use netstat? ;)

It's more than Red Hat. Broadcom has removed not only netstat but ifconfig and other tools like vim. Get used to nano. ;)

You understand very well that we are talking about the possibility of working with netstat in general and not about whether it is pre-installed or not.
 
If you look at the help page for ss, you'll notice that it has far fewer command line switches than netstat, meaning it has fewer options.
 
90 to 95% of Linux distributions have deprecated every normal "network" thing. ifconfig? install net-tools. netstat? install something else
Current Linux distros is "use the ip command for everything because we don't like the traditional crap".

Going back to the OP:
netstat on *BSD is not netstat on *Linux-distro, so options will be different.

If you want to know how Linux does crap, look at the Linux tools.
If you want to know how *BSD does stuff, look at the *BSD tools.
 
I cant install ss
sudo pkg install ss

I use this 5 % - Arch - rolling,no painful updates to a new version
,newest kernels, only in Gentoo newer kernel but gentoo is a pain to install
:) And what 95 percent can there be if the bulk of Linuxes are forks from Debian and Red Hat?Only Open Suse, Gentoo and Arch have their own packages.

ss is for Linux? You should try BSD tools mentioned above instead.
 
Oh well, I'll control the local network from a local computer on Arch (netstat) and launch tcpdump on server's freebsd
