Get the time when nohup R program finishes

I want to get the time when program starts and finishes. But it always show the same time. Here is my shell script. But it always show that `START TIME` is same as `END TIME`.

Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_4" "L_3" "L_4")
subject="The job is finished"
START=$(date +"r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt';echo 'The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME =`date +"%r"` | mutt zwang10@mtu.edu -s '${host_list[0]} - Job ${program[0]}.R finished' -a '$address/${program[0]}_sh.txt';"

I assume that is the start time, so you can see the the part ... END TIME =`date +"%r"` was executed at the time of invocation of the ssh command. I think you need to split it into 2 parts:

Code:

....
START=$(date +"r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt'"
END=$(date +"r")
echo "The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME = $END" | mutt zwang10@mtu.edu -s "${host_list[0]} - Job ${program[0]}.R finished" -a "$address/${program[0]}_sh.txt"

(not tested)
It will execute the echo and mutt on the local host, and your original example executed them on the remote host (if that counts).

I tried you code as following

Code:

host_list=("c15-0330-01.ad.mtu.edu" "c15-0330-02.ad.mtu.edu" "c15-0330-03.ad.mtu.edu" "c15-0330-04.ad.mtu.edu")
program=("L_1" "L_4" "L_3" "L_4")
subject="The job is finished"
START=$(date +"%r")
address="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"
ssh -f "${host_list[0]}" "cd '$address' && nohup Rscript '${program[0]}.R' > '${program[0]}_sh.txt'"
END=$(date +"r")
echo "The job\n $address\n${program[0]} is finished\nSTART TIME = $START\n' END TIME = $END" | mutt zwang10@mtu.edu -s "${host_list[0]} - Job ${program[0]}.R finished" -a "$address/${program[0]}_sh.txt"

But it sends me email when the program starts. When program finishes, it does not send me email. Here is the email

looks like it depends on that Rscript but we know nothing about that.
