AIX

I need to login to several AIX boxes .... I use putty for that and I am losing the configurations as I logout. For ex: I like to work with emacs editor, as AIX comes default with ksh , I set it using set -o emacs, once I log out and login back I am back again in ksh ...

Put whatever you want to have set into the file .kshrc in your $HOME directory. This file (don't forget to set the executable-bit) is executed every time a new shell is started by your user.

Btw. and for clarification: when issuing "set -o emacs" you do NOT leave the Korn shell, just change the way the commandline can be edited.

I hope this helps.

I dont have .kshrc file in my home dir , can I create it and check.

I am not sure if this is known to you (if it is: sorry about wasting your time), but you won't see files named starting with a dot "." if you do an "ls -l" as a non-root user. Use "ls -la" to see them. In fact this is what the "-a" option is for. For the root user "-a" is the default in ls.

You can create the file using your favourite text editor, it is like any other shell script.

Here is a sample .kshrc script which you can use as a starting point:

Code:

set -o vi             # my preference, change it to "emacs" if you like

unalias rm            # many systems have "rm" aliased to "rm -i" to enforce
                      # interactive use of rm, but i dislike this. I like living dangerously.

alias l='ls -lai'     # this is a nifty one, which saves typing

PS1='# '              # set the shell prompt

save this to the file ".kshrc", set the executable bit and excecute by ". ./.kshrc" to activate it.

I hope this helps.

You can also use your .profile to set these configurations... also if you need to use a variable or update your path, etc... remember to export the variable...

For example add this to your .profile to add the bin directory from your home directory in your path...

Code:

export PATH=$PATH:~/bin

ahem...:no - at least not quite

".profile" is executed every time the user logs on, whereas ".kshrc" is executed every time a new ksh instance starts. Of course, logging on will also start a new shell (which is started by the login process), so in this (but only in this) instance both events occur at the same time. It is a good idea to put

Code:

. ~/.kshrc

at the end of the ".profile" script, just in case.

But except for this the two events are quite different.

I hope this helps.

Thanks a lot Gurus (masters)... :-) , I really learnt a lot from this small topic once again thanks for sharing the info.

I have a quick question again ;-)

I have the following script in my $HOME :

alias l='ls -lai'
EDITOR=emacs # This is my fave editor
alias c='clear'
clear
alias x='exit'

when I type
$ oslevel -r command - I get the result but with the screen cleared
but when I use with sudo , I have no issues
$ sudo oslevel -r ....... i get the result at the next line......

anything wrong in the .kshrc profile
