Enabling the arrow keys, insert key, and page up/page down keys in "vi" has to be done in a ".exrc" file in your home directory. See "man ex". The contents of the ".exrc" file depend on your terminal (or terminal emulator). For the root account I have more than one saved version and copy the one which matches the value of $TERM.
First check whether you have a ".exrc" file already to see whether you are going to edit it or create it.
The format of a .exrc file is very basic:
map key_you_press key_in_vi
map key_you_press key_in_vi
The "key_you_press" is the exact control sequence generated when you press that key. The "key_in_vi" is the key (e.g. "k") you would press in vi to get that effect.
I don't know how to generate a ".exrc" file using "vi". I use "echo" to generate mine.

Thanks

In IBM Mainframe they have something called ACF2 rule which is essentially used to control the dataset access. It is kind of a list-based access control for mainframe datasets.
Is there anything equivalent to ACF2 available in Unix ?
Thanks

I moved to a Linux system from Windows a few months ago. Most of the programs I had been using were already native to Linux (Firefox, the GIMP, Pari, etc.) and most others I found a close enough program (Crimson Editor -> gedit, Visual Studio -> KDevelop, Primo -> Morain's ECPP).

I need to mount a replicated nfs4 export on a number of AIX and Redhat hosts. To get the failover on the clients working smoothly, I need to change certain values on the AIX boxes like nfs_v4_fail_over_timeout, timeo and retrans values.
