Crontab and shell scripts to implement Linux timing tasks __linux

The writing of Linux shell scripts

VI test.sh

#!/bin/bash

###################
. /etc/profile
. ~/.bash_profile
##################

Path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Cd/home/huaxia/syslog2db&&ruby app.rb Stop
Cd/home/huaxia/syslog2db&&ruby app.rb Start

After saving, authorize chmod +x./test.sh

Execute./TEST.SH can run correctly the presentation script is written correctly

Linux Crotab Edit

Input CROTAB-E into the scheduled task editing interface
Write the script that needs to be run, and the time the configuration runs is as follows:
* 7 * * * * * */root/test.sh>/dev/null 2>&1 (indicates that the script is run at 7 o ' clock every day, the script is in the full path,> after the mask stdout and stderr output)
(You can specify the path of the output when debugging: * 7 * * * */root/test.sh>>/home/test.txt)


Environment variable Configuration Statement Path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Personally think that you have to add (if you encounter a timer does not work, but the manual execution of the script normally can be judged that the environment variable is not introduced)
