Schedule run a jar file in command prompt - jar

I want to run a jar file on every Monday that can be executed from command prompt only not by mouse double click. I have used windows task scheduler and it is showing the last run time of file but it is not able to perform the desired action!

Running several R scripts at once using .bat file with CMD BATCH?

I wanted to use a Windows .bat file to run several R scripts and schedule it using windows scheduler.
However, when I test using windows scheduler, everything executes but the files that the R scripts should create are never created. Instead, when I double-click on the .bat file itself it works fine. My goal is for several scripts to just run overnight without me going in and running each one of them manually one-by-one.
If I were to add a second line to the .bat file that would make it run a second script, would this execute only after the first is complete? If not, would I be able to delay the second until the first finishes somehow?? For instance, my .bat file looks like this:
"C:\Program Files\R\R-3.4.2\bin\x64\R.exe" CMD BATCH C:\Users\gma\Desktop\R_Task\script1.R
"C:\Program Files\R\R-3.4.2\bin\x64\R.exe" CMD BATCH C:\Users\gma\Desktop\R_Task\script2.R
I used the answer provided by #Gautam (R taskscheduleR not executing script) to get this far

Scheduling R scripts in Task Scheduler - CMD runs, but task does not complete

I am trying to automate R scripts in Windows Task Scheduler. I've finally managed to get the program to run, sort of, but it doesn't complete its task.
When task scheduler runs, the CMD windows pops up and I can see it installing the necessary packages to run the script, but the task doesn't actually complete. It is supposed to update a spreadsheet, which works when I run the script in R Studio but does not work when I run it through Task Scheduler.
I am running the script through Windows Task Scheduler as follows:
Action: Start a Program
Program/script:"C:\R-4.0.3\bin\Rscript.exe"
Add arguments: "C:\Documents\Options-Measurement.R"
This may be related to the working directory. Could you please add something like print(getwd()) to your script and check if it is the desired working directory?

How to debug this scheduled .bat task in task scheduler using cmd and log file?

I'm trying to basically run the following .bat file as a scheduled task, while also logging errors in a .txt file:
In the 'program/script' box, I just have cmd. Then in the add arguments box I have:
/k ""T:\Some_folder\mybatchfile.bat" >>"T:\somelog.txt" 2>&1"
This had been working just fine originally before I tried to add the log function and calling cmd explicitly as seen in several posts, but I'd really like to add this function. I'm using /k for now so that I can watch the cmd window as things happen, but plan to replace it with /c so it closes when its done.
I tried many permutations of where my quotation marks are but am not having a lot of luck. I'm also intentionally using >> vs > in order to append the log, not overwrite it.
The contents of the .bat file are basically:
"C:\RDirectory\R.exe" CMD BATCH "T:\Some_folder1\Preworkforbatch.R"
copy T:\Some_folder2\some_data.csv "C:\Users\ABC1\Another_folder"
copy T:\Some_folder3\some_more_data*.csv "C:\Users\ABC1\Another_folder"
I'm wondering if part of it is that T is a network folder that is mapped? Thanks for your help.
edit:
Here is more info on the task:
"T:\Some_folder\mybatchfile.bat" >> "T:\somelog.txt" 2>&1
When redirecting the output of a batch file to a log file you will not see as much output in the cmd window. You have to repeatedly open, close, open the log file to see your progress. Use the title command in your batch to display progress info in the cmd window.
title This is %~F0. The time is %time%. The date is %date%. SLEEP 3600 FOR :RECORDRADIO
Ok this ended up working for me, by editing the batch file itself, and just running the batch file (not cmd explicitly) in the task scheduler:
mybatchfile.bat:
#echo on
"C:\RDirectory\R.exe" CMD BATCH "T:\Some_folder1\Preworkforbatch.R" >> "C:\Users\ABC1\Logfolder\mylog.txt" 2>&1
copy T:\Some_folder2\some_data.csv "C:\Users\ABC1\Another_folder" >> "C:\Users\ABC1\Logfolder\mylog.txt" 2>&1
copy T:\Some_folder3\some_more_data*.csv "C:\Users\ABC1\Another_folder" >> "C:\Users\ABC1\Logfolder\mylog.txt" 2>&1
Writing the log file to the network was causing errors. Writing to the local computer solved this issue. Not using double quotes also was key, instead just quotes around the file/path. This setup gives me an output for each line, so for every line 2>71 shows up, I get an output if there's an error or a completion message.
This is what the task scheduler looks like:

nohup command getting permission issues

I am trying to run a filewatcher.sh script in background. It further invokes a java code through a jar file.
Whenever I run the command("nohup sh filewatcher.sh") through terminal, everything is ok. I have to hit enter two times so the output file is appended to nohup.out. But whenever I try to run the equivalent command("nohup filewatcher.sh >> nohup.out < /dev/null &") from a shell script automate.sh, I get following permission error.
error-log. Click to see snippet.
Could this an issue of permission for the automate.sh?
I have crossed check to see this script is having same permissions and ownership as the user when I log in and enter the nohup command from command line.
I also checked the ownership of the folders where the files are getting moved but everything is having same permissions and ownership.

Automating R to run scripts

I'm basically looking for any way to automatically run R scripts just like it would run as if I was copy and pasting it into console. I've tried the package 'taskscheduleR' however it just seems to output to a log file in the directory which isn't as if I were to just run it inside the Rstudio application.
An example might be, say I want to get the last closing stock prices of 5 stocks each night, then the script in Rstudio and have the variables there and all of the code would be in the script file.
Any thoughts?
I would suggest the in-built Task Scheduler application if you using Windows.
Create a task that will run a batchscript file. This batchscript file has only 1 line which executes the Rscript you want. Set it to run each night (or whatever time you want).
I am not that well-versed in linux and MacOS but here's what I know:
Linux has cron. Add a job to crontab with your preferred timing and execute your script 'path/to/bin/r /path/to/script.r'
MacOS has Automator + iCal (for scheduling). It also has crontab like Linux.
