    Hi,

    Creating Shell Script
    Cron-Job
    Application: LMsensors

    Shell Script funktions:
    1. If CPU hot'er than X then sendmail and log
    2. If CPU hot'er than Y then sendmail, log and shutdown

    Problems:
    1. Script works regarding log'ing and shut'ing down - but I'm having trouble getting the script to sendmail (and to put text into the mail/sending msg.txt)

    Normally you would use the sendmail compatibility binary on a postfix server to send mails from a shell script. So the command to send mail is:

    /usr/sbin/sendmail

    and not:

    /usr/sbin/ssmtp
