script: top via email

[Hubert Feller]

Hi all
I wanted to write a small script to send the output of the top -d 1 - command via email to our unix-inbox for monitoring.
There is no problem to run this script manually, but when i tried to trigger it within crontab it gives me an error. Here the critical line:
/bin/top -d 1 | mailx -s "Output of top-command. Please check!" $EMAIL
and here the error:
Sorry, I need to know a more specific terminal type than 'unknown'.
I added a statement like TERM="hpterm" but id didn't help.
Any ideas?
Thanks for your help

You are sending the output of top to the standard output. There is no terminal attached so this is probably your problem.

Try using the "-f filename" option to "top" to output to a file and then e-mail that file.

Mark's suggestion should work but if you don't want to go via an intemediate file, so should your idea of TERM="hpterm".
Where did you put this ?

It needs to precede the top command, as in
TERM=hpterm /bin/top -d 1 | /usr/bin/mailx -s "Output of top-command. Please check!" $EMAIL

Thanks for your help guys

i must have sit on my eyes when I looked at the man-page of the top command. But finally the -f - option solved the problem.

Have a nice weekend

Just for info

I found out that the -f - option of the top-command is not documented in HP-UX 10.20 but can be found in HP-UX 11.00. That's why I didn't get it yesterday.
