Full Discussion: prepend timestamp to continiously updating log file

@Corona688 - Your solution works if the log file which you took as input is already created. But in this case, the log file will be updating always whenever a transaction is processed.

Also, per your suggestion, I need to create another log file which I do not want to.

I want to create only once when the process runs and output the detail of process to log with time stamp before each line.

FYI, the command is inside a shell script and all this is desired when the script is executed.

And, I will be killing the process may be once in a day.
