Linux crontab command Add Kettle Job scheduled task

1. Ensure that the job $KETTLE _HOME/KITCHEN.SH-FILE=/DATA1/TESTDATA/TESTKJB.KJB or converted $KETTLE _home/pan.sh-file=/data1/testdata/ TESTKTR.KTR can perform normally under Linux

This step is configured correctly in the JDK (Ps. Optional configuration of the kettle environment variable, primarily the home directory where the locator is located, without having to refer to the absolute path each time),

There are few other issues where the current user has execute permission for the corresponding *.sh file.

2. Write the execron.sh script that executes the kettle job or transformation, especially in the Red Callout section, in the shell script to perform the operation to refresh the current system environment variables,

The current environment variable is not read because the crontab command executes the script

#!/bin/bash
Source/etc/profile
# $KETTLE _HOME/PAN.SH-FILE=/DATA1/TESTDATA/TESTKTR.KTR

$KETTLE _HOME/KITCHEN.SH-FILE=/DATA1/TESTDATA/TESTKJB.KJB

3. Crontab-e into the scheduled task edit file, the command format is shown below:
