How to derive procedures from SMIT
Actually the "complex script" is relatively easy to decipher. Hitting <F6> makes SMIT show what it would execute. This is the case since the first AIX version i used (3.2.3) and will perhaps only change when hell freezes over. ;-))

An easy way to find out what SMIT exactly does is: fill the mask with easily distinguishable values, press <F6> and in the last line you see the real call with your values. In the script above (which is called by this line) you can now find out where and how these values go and near the end of the "cmd_to_exec" you find the real OS-level command: "chdev -l ...."

Specifically for your problem i have done it for you. How to change routes according to SMIT:

Code:
chdev -l inet0 -a route=<destination>,-hopcount,<hopcount>,-netmask,<netmask>,-if,<interface>,,,,<destination>,<gateway>

If you do not need a specific peace of information or want to use defaults you can leave that part out. For instance if you do not want to specify a hopcount replace "-hopcount,<hopcount>" with "".

By the way: if all your values are always the same you can also do the following: use SMIT do do it once on a machine. Then have a look in the file "smit.script" in your home directory. From there you can copy the function declaration along with the command to execute the function with certain values, to a separate file, name it "mychange.sh", give it execute rights and use it over and over again.

I hope this helps.

PS: wouldn't that thread have been better placed in the AIX forum? SMIT is a very specific AIX tool, which does not exist outside AIX boxes. Just a thought.
