What system are you running? I am running pretty much standard Debian
11, and I notice these differences:
You appear to have root's home at /home/root. Mine is at /root, and I
have no /home/root.
root@jhegaala:~# cd
root@jhegaala:~# pwd
/root
root@jhegaala:~# ll /home/
total 28
drwxr-xr-x 4 root root 4096 Oct 10 2021 ./
drwxr-xr-x 19 root root 4096 Oct 19 06:27 ../
drwxr-xr-x 50 charles charles 4096 Nov 10 08:00 charles/
drwx------ 2 root root 16384 Oct 10 2021 lost+found/
root@jhegaala:~#
which finds ping at /usr/bin/ping.
root@jhegaala:~# which ping
/usr/bin/ping
root@jhegaala:~#
although the two are the same:
root@jhegaala:~# ls -i /bin/ping /usr/bin/ping
7607442 /bin/ping 7607442 /usr/bin/ping
root@jhegaala:~#
I get a different response when I try to execute a program that the
shell cannot find.
root@jhegaala:~# foo
-bash: foo: command not found
root@jhegaala:~#
And, of course, I have no problem running ping without specifying a
full path to the executable.
root@jhegaala:~# ping -c 3 chaffee

Does anybody read signatures any more?
