Solaris has rename(2) also.

Yes, every OS does killall different.  That why many of us write our own
utilities.

Ah, I see it on 9 too.  8 doesn't have it.  I have 2.6, 8, 9 and 10 to
choose from here.  And I think there's a 7 about to be commissioned.

Solaris 8-10 have the Software companion CD.  Installs in /opt/sfw or
/usr/sfw and has many commands you want.  gcc, top, sudo, tcpdump, nmap,
samba.  Sun patches can apply though it's "not supported".  I recommend them
because they come from Sun.

Sun has released Sun Studio 11 with thier optimized C, C++, Fortran
compilers and IDE for free.  There is also a Linux version but it may be
just the IDE so far.

Rename isn't part of GNU fileutils (at least the Solaris version):
$ pkgchk -l SFWgfile | grep rena
