question pn Password!!
Hi Unix gurus,
I have one question for you on passowrd:

I have one script which takes care of configuring SSH on some 200 servers. But for 200 times it prompts for password and always I enter the same password for all the 200 servers. I want to know if i can store the password in a variable or a file and whenever system prompts for the password then it must take the password value from the variable or file so that I can avoid typing the password. Please help and advice.

Warm Regards,
RK

That depends on how and where you wish to give password. For example, to the passwd command, to ftp, to telnet, to ssh, etc.

You may have to use Expect in some cases.
