If you are referring to the setting of $PATH during logon, or just invoking a 
shell, my PATH includes the directory in which both netstat and onetstat reside 
(/bin).  See the following tests:


(base) [bash] DVFJS@ZOSD ~ $ printenv PATH

/u/dvfjs/golang/bin:/u/dvfjs/miniconda/bin:/u/dvfjs/miniconda/condabin:/u/dvfjs/bin:/bin:/usr/sbin:/usr/lpp/java/J8.0_64/bin:/_PRDS/PYTHON/SCYPH311/pyz/bin:.

(base) [bash] DVFJS@ZOSD ~ $ printenv SHELL

/u/dvfjs/miniconda/bin/bash

(base) [bash] DVFJS@ZOSD ~ $ onetstat -P 1234

[Note that the ls -F option "Puts a / after each directory name, a * after 
every executable file, a | after every FIFO file, a @ after every symbolic 
link, and a = after every socket. It also puts an & character after an external

Thus my "guess" that in bash (but not in sh or tcsh) the file names that are 
external links are not found (unless the directory is explicitly specified.

Try it yourself (if you have bash available).

Check your PATH environment variable.
If the directory where 'netstat' resides is not in your PATH, then
you'll get "command not found".
There's nothing about BASH or ZSH which would preclude 'netstat' or
'onetstat' from working.

One of the [un]fortunate things about the myriad command shells
available is that most have their own unique way of profiling. (Though
most *can* follow the original rules.)
That is, if you have $HOME/.bash_profile, and BASH is your login shell,
it will get sourced when you log-on rather than $HOME/.profile.
You very possibly have different profiling for BASH, ZSH, and stock
/bin/sh.
As a rule, I either remove $HOME/.bash_profile or make it a sym-link to
$HOME/.profile.

I do use ZSH, but less often, so am less familiar with how it works on
this point.

ORIGINALLY, /etc/profile gets sourced when you log-on. If you then also
have $HOME/.profile, it gets sourced afterward (so you can override
system profiling with your own customizations).

A related thing is "RC files", like $HOME/.bashrc. The "RC files" get
sourced *every* time a shell is spawned, not just when you log-on.
Many newcomers to Unix/Linux/POSIX don't know the difference between the
profiles and the RC files, so they throw all of the profiling into
(e.g.) $HOME/.bashrc. It's kinda counter-productive. The RC files are
for settings which cannot be "inherited" for one reason or another.

It gets worse with graphical logon. (But need not! Just that nobody
bothered to set things right for the graphical logon logic.)

Keep it simple and stick with the standards. Avoid shiny things and
feechers which cause konfoozhun.
