What Others Think

Hi, I wasn't able to reproduce your commando on a RHEL 5.5. Can you please add more detailed instructions? Thanks, ztank

See also screen -x for a more advanced solution where all sharing persons can type in the session. (Although it needs elaborate setup to work with different users.)

Nice thinking but not really working here on a CentOS 5.3 box.

ztank, read the man pages for the 'script' command, and much will become clear. Essentially, script records all keystrokes, stdin and stdout, including timing information. The '-f' option allows you to specify a file where all of this information will be stored. Catting that file will send all of this back out to the screen, echoed at the same rate that the commands were typed in. You will have to make sure that script is installed on your box for this command to work. To test this: in one terminal, mkfifo foo in a second terminal cat foo in the first terminal script -f foo Then run several commands in the first terminal, and they will be echoed in both terminal 1 and terminal 2.

if you want to keep a transcript of the session, you can simply run script -f asdf then have observers run tail -f asdf (In this case asdf is *not* a fifo) For some reason, there is a slight delay between typing and seeing text echo under 'tail -f asdf' (whereas I saw no delay when catting the fifo 'foo').

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
