How is that in any way better than "sudo -i" (which I already suggested,
and which avoids a needless extra command invocation)?

If you need to run a lot of commands as root, the easiest sudo method is
simply 'sudo su -' which makes you into root. The trailing '-' does a
login which replaces your environment with root's.

I find sudo on Ubuntu much easier to use than sudo on SL6.
By default on Ubuntu you can run succeccive sudo commands without
reentering the password each time.
I never figured out how to do that with SL.
That doesn't sound like default behaviour for sudo on SL6. I've been
using it for years, and haven't had the password issue you mention.
Since sudo is pretty old, stable code, there likely aren't any
differences between its implementation in RHEL/SL vs Debian/Ubuntu,
other than the content of the /etc/sudoers file. I'd check that against
the distro's clean, initial configuration, and see what's broken.
When I need to use pipes or redirect stdin and stdout as root,
a simple "sudo bash" first solves those issues.
You can use "sudo -i" to accomplish the same thing, but with perhaps
more "sane" initial setup, since it simulates a login.
