[ale] line timestamp command

[Scott Plante]

I can't modify the process itself, or I'd just add the timestamp inside it. I can modify the script that calls the process, so if there's a way of routing it's output to the Linux logging that might be an option. I don't want these messages mixed in with /var/log/messages though. Can you point me towards something? Or just a command name or something to make the googling easier?

Can you modify the process to just write to standard logging?

Does anyone happen to know of a command line tool that will read lines from standard input and write them to std out, pre-pending a timestamp? I have a process that emits messages to std out periodically as it processes and I'd like to write that to a log file, but with a time at the start of the line. I could do it with a script but a nice little command would be better, if it exists. 


I'm looking for something that would perform the function of this script, maybe with an option for format: 


while read line; 
do 
echo $(date +"%D %T") "$line"; 
done
