Can not send cron output to the screen
I have been researching this for hours without success. I am trying to do what I thought was a simple task, but can not make it work. Here is what I am trying to:
I set up a cron job that runs a file that displays the uptime. I would like to send the the output to the screen and not to mail, or a file. I can do both now, but have not been able to find a way to sent the output to the screen. If possible I would like to send the output to both the screen and to a file.
To send to a screen I am doing this:
0 * * * * /home/user/file > /var/log/file 2>&1
What I need is to be able to also send the output to the screen. I know it is possible.
Thanks, tryingHarder

Try the command "xmessage"
It displays a dialogue box, and you can have the output of commands displayed.
man xmessage for details

Xmessage works if there's an X Windows GUI running. If there isn't, such as on a server box, you ccan try sending the output to /dev/tty1 (the terminal device), e.g. echo foo > /dev/tty1. Make sure the cron job runs as someone with write access to the tty device.

This was the correct answer to my quesiton about sending cron output to the screen:

This is really a great place to learn about linux!
