Shell Mini-Version Monitoring script

wrote a Shell version Mini monitoring scripts, purely to share with you the study , be interested in learning Shell can look down. (*_*)

Total 3 a script file service.sh, daemon.sh, tcp.sh

Implemented a number of basic functions: port monitoring, survival monitoring, off-line mail alarm, re-launch email notification

will be 3 files in a single directory

settings: In tcp.sh you can set the email notification address, and the number of messages

Run: ./service.sh Start

The main file code is as follows:
