You can change path info in /etc/profile to make it system-wide.
As for ~/.profile, I tried all the shells listed in /etc/shells, and none
of them ran the .profile I created as a test.

I don't see why UNIX like systems have to have so many bin (and other)
directories. Let's see, there is /bin, /usr/bin, /usr/local/bin,
/opt/local/bin, the same variants for sbin, plus executables in
/usr/libexec, /usr/local/libexec and (for shame) /etc.

Sheesh!

Thankfully someone invented the 'which' and 'whereis' commands.

JJ

It's in our blood. Programmers like to categorize things. The
downside is that a lot of apps like to tread all over that
categorization. Ah... life.

Paraphrasing from the green book (LAH) and adding a last one of my own:

* /bin -- commands needed for minimal system operability
* /sbin -- commands for booting, repairing, or recovering the system
* /usr/local/bin -- local executables (site-specific)
* /usr/local/sbin -- statically-linked local (site-specific) system
maintenance commands
* /usr/sbin -- less essential commands for system admin and repair
* ~/bin -- your own commands :)
