How Can I Add Dates To Nohup Log Files Lines

Question

I'm running python on my server. I want to add date and time info to my nohup log file's lines.

Log file content similar to what I want to do (inside log file):

09/09/2023 07:13 Traceback (most recent call last):
09/09/2023 07:13 //Some Error
09/09/2023 07:13 //Error...

Is it possible to do this? So how?

Although not a very perfect solution, I did something like this. I created a .sh file and added this codes.

#!/bin/bash
Output File
output_file="nohup_output"
nohup command > "$output_file" 2>&1 &
while true
do
if tail -n 1 &quot;$output_file&quot; | grep -qF &quot;$current_datetime&quot;; then
    sleep 1
else
    tail -n 0 -f &quot;$output_file&quot; | while read -r line; do
current_datetime=$(date +&quot;[%Y-%m-%d %H:%M:%S]&quot;)
echo &quot;$current_datetime $line&quot;
truncate -s 0 nohup_output # To delete inside the nohup_output file
done &gt;&gt; &quot;$output_file.log&quot;
fi

done

In this way, I got printouts containing the date and time as I wanted.
