I think you are right. The only remaining argument for specifying the
complete path I have read about is as below.
There might be the situation with different binaries but similar
names. For example /usr/bin/nc is different to /bin/nc.
But such a system should be a nightmare and I doubt if you can find
such an installation in the wild.

I have a few scripts which should run at Linux and FreeBSD. In the
past I have used uname to distinguish the platforms. This works but it
is bulky and ugly. Things will be fine if I concat the PATH required
for both systems and follow your advise.

Thank you and kind regards,
Christoph
