How to schedule an R Script Cronjob in a linux server? [closed]

Question

I am trying to schedule a cronjob to execute an R Script in a linux server. I have achieved to type the commands in the server manually and it works. To do so i have to type the following commands:

1. root@debian:~# cd /home/script2
2. root@debian:/home/script2# Rscript scriptSecos.R

How can i specify a cronjob that will execute the previous commands, once a day?

Thank you.

Answer 1

The following cron job will run Rscript scriptSecos.R from the path /home/script2, once a day, at 0:00 (midnight).

0 0 * * * cd /home/script2; Rscript scriptSecos.R >/dev/null 2>&1

If you want to save the output of the script to a file, change >/dev/null with >/path/to/file.

You can copy and paste this cronjob in your crontab file (You can open the file by using command crontab –e)

Answer 2

The following site provides useful reference information for crontab

With your example, the following will run the job at 3 am everyday.

00      03      *       *       *       Rscript /home/script2/scriptSecos.R

Answer 3

add cron as below.

eg:

15 23 * * * Rscript /home/script2/scriptSecos.R  >/dev/null 2>&1

you have to mention running script type.Then allow cron logs and check its running or not
