I don't believe that any of the basic commands are GNU (cp, find, etc) unless you have installed them yourself.

The man pages should give you the required info. Example from the man page for the GNU version of xargs;

"This manual page documents the GNU version of xargs"

Another for the GNU version of find;

"This manual page documents the GNU version of find"

Also, if your trying to use a GNU feature and it isn't working; you probably don't have the GNU version.

When you are setting up the system then everything is fine.

But imagine the situation when you are given a job to do.

Now comes the main problem.
You try some features which are not working, it gives random errors, you don't know that these features are specific to Gnu and vice versa.
On Googling you find out that these are specific to Gnu.

So now the only option that i have is to check the man pages to find out whether mine commands are Gnu or not.

Okay i will try you update you all.

Simple.

(1) only install GNU software from HP (http://www.software.hp.com/) or the porting sites (http://hpux.ee.ualberta.ca/hppd/hpux/Languages/python-2.3.3/) using swinstall (depot files).
(2) use swlist to determine what OTHER packages you have installed other than the normal Hp stuff.
(3) check your PATH variable. Use the command "which" (which command is found in your PATH first) and "whereis" (to determine what commands are available in your PATH).
(4) GNU commands typically have a "--version" option

That means all Gnu commands have the -version option.

If this is right then its very easy to find out whether my commnad is Gnu one or not.

"typically" doesn't mean "ALL". And not all commands that have a "--version" option mean that they are GNU: an example is perl.
