Version of awk in Solaris 10?

Question

I have found that there are
/usr/bin/awk (hard linked with /bin/awk)
/usr/bin/nawk (hard linked with /bin/nawk)
/usr/bin/oawk (hard linked with /bin/oawk)
What are they?
I wanna ask what version of awk does Solaris 10 use?

Answer 1

/usr/bin/awk (hard linked with /bin/awk)
/usr/bin/oawk (hard linked with /bin/oawk)awk & oawk - equals (hardlinked), this is "old" awk man awk
/usr/bin/nawk (hard linked with /bin/nawk)
and /usr/xpg4/bin/awkxpg4 awk & nawk - nearly equals, this is "new" awk man nawk
I wanna ask what version of awk does Solaris 10 use?Solaris and you can use both. There are some "awk" language differences (http://www.gnu.org/software/gawk/manual/gawk.html#Language-History) and implementation constrains (such as input line length).
The precompiled gawk is avaiable from blastwave (http://www.blastwave.org/packages.php/gawk).
