Crontab 不执行 R 脚本

Question

I'm trying to setup a Cron job on my system by adding the following line

17 12 * * * Rscript ~/path/to/file/script.R > ~/output_`date +\%d\%m\%y`.txt 2>&1

yet, I cannot see the file the output is being written to. I've consulted the following answers, but to no avail:

Why did my crontab not trigger

CronJob not running

When I run the following command on the terminal:

Rscript ~/path/to/file/script.R > ~/output_`date +\%d\%m\%y`.txt 2>&1

I get the output file as expected. I also added the following line to crontab:

* * * * * echo hi > ~/output.txt 2>&1

and it works just fine. I'm not sure what is wrong with the first command. Any help would be appreciated. Thanks.

Answer 1

Try Below trick, Create one script script.sh like below -

cat script.sh
Rscript ~/path/to/file/script.R > ~/output_$(date +\%d\%m\%y).txt 2>&1

And then create below entry in crontab.

17 12 * * * /bin/bash /path/to/script.sh

我解决了这个问题通过更换Rscript在我的crontab用/usr/local/bin/Rscript （或任何你RSCRIPT所在-做which Rscript找出）。
