zone copy, aka zcp.

After messing around with zones for a few minutes it became clear that it would be really useful if there was a zcp command that worked just like scp(1) but used zlogin as the transport rather than using ssh. For those cases when you are root and don't want to mess with ssh authorizations since you know you can zlogin without a password anyway.

Specifically I wanted to be able to do:

# zcp  /etc/resolv.conf bookable-129-156-208-37.uk:/etc

Well it turns out that this is really easy to do. The trick is to let scp(1) do the heavy lifting for you and use zlogin(1) act as your transport. So I knocked together this script. You need to install it on your path called “zcp” and then make a hard link in the same directory called “zsh”. For example:

# /usr/sfw/bin/wget --quiet http://blogs.sun.com/chrisg/resource/zcp.sh
# cp zcp.sh /usr/local/bin/zcp 
# ln /usr/local/bin/zcp /usr/local/bin/zsh
# chmod 755  /usr/local/bin/zsh

Now the glorious simplicity of zcp, I'll even trhow in recursvice copy for free:

# zcp -r /etc/inet bookable-129-156-208-37.uk:/tmp

# 

I'll file and RFE for this to go into Solaris and update this entry when I have the number.

Update: The Bug ID is 6673792. The script now also supports zsync and zdist although niether of those have been tested yet.
