问题
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:
- root@debian:~# cd /home/script2
- root@debian:/home/script2# Rscript scriptSecos.R
How can i specify a cronjob that will execute the previous commands, once a day?
Thank you.
回答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)

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
回答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
