unix script command

James W. Taylor — Wed, 10 Jan 2001 22:01:51 GMT

I was using the script command from the console to record the installation of a product. When I exited from the script, the console froze and I had to reboot the server. This happened multiple times. The last time instead of a reboot I went to another server and did an rlogin. I killed the script process and the console came back. Is this expected behavior from the console? What can I do to avoid this in the future?

Hi James

It looks like your script re-executed. What were you running?

The console should only be used as a last resort and not to perform tasks that can be run from a telnet login.

We all have done it and of course learnt from it.
You are not the first and will not be the last.

Best wishes

Paula

Hi James,

Using the 'script' command from the console isn't a very good idea, as you realized.
Maybe that system reboot was a bit too expeditive solution. You could have tried a terminal reset.

I guess that your installation program is probably addressing some of the terminal formatting capabilities which are not properly passed through by 'script'. This could result in an terminal lock, you know that a simple could apparently freeze the terminal (in fact it's simply freezing the output if XON-XOFF flow control is enabled)

Next time, if you want to use 'script', you'd better use it from a remote login or telnet terminal as this will be a lot easier to 'kill' in case of a problem.

Best regards,

Dan

If your console gets locked a way to reset it is:

1. power it off
2. turn it on keeping CTRL-D ( or CTRL-ALT-D) pressed for a couple a secconds (if you have any other spare finger :-))
