cron 作业未在数字海洋液滴中以 root 用户身份运行

Question

I created this test bash script

#! /bin/bash

echo "hello"

mkdir  "/karan/washere"

cron job i created, i want to run this cron job to run every min and want the log

#testing if cron job workes or not 
1 * * * * /user/local/bin/bash /root/test.sh  &> /root/crontest.log

I am signed in the droplet as root user

I also have given the permission for the script, using

sudo chmod u+x test.sh

I tried to log the syslog using

sudo grep CRON /var/log/syslog

but didn't show there also,

let me know if you need any more info or other context,

Answer 1

cron uses sh to interpret the commands, not bash . sh has less features and the &> is not valid in sh .

A better way for your line in the crontab would be:

1 * * * * /user/local/bin/bash /root/test.sh  >> /root/crontest.log 2>> /root/crontest.err

This will append to the logging instead of overwriting, and it will separate log from errors.

If you want, however, you can force cron to use bash instead of sh . Your crontab should then be:

SHELL=/bin/bash
#testing if cron job workes or not 
1 * * * * /user/local/bin/bash /root/test.sh  &> /root/crontest.log
