See if file exists and if not create it
Hi,
I am using an expect script to roll out an ssh key to multiple servers. I have a problem as on some of them the authorized_keys file exists and on some it doesn't. Where it exists I need to >> the key in and where it doesn't I need to create the file then sftp the file over.
So I need some help ! Is there a simple script using a 'for' loop which I can use to login to mutltiple server and check if a file exists (and if not create it?)
As usual any help much appreciated

Cheers
G

You should be able to append on every server. If the file doesn't exist, it will create it. You really then only need to be sure of setting the permissions correctly for the key to be considered as secure and allow the various commands to work.

Also look at "ssh-copy-id".
