Create log for finished processes
Hi, I'm doing a script that generate some background process like

Code:
for file in `find $dir -type f -maxdepth 1 -mtime -1`;
do
    exp="java -cp process.jar testing $file &"
    eval $exp
    echo $! #Get the PID
    echo $(basename $file) >> log
done

Is there a way to know when those generated process are finished? As you can see at this point in the log file the file names are stored, but when the process is started. I want to store the file names when they're finished. Any hint? Maybe a little perl or something?

Thank you

Store the background process pid into a variable and check if the process still exists through the ps -p $BG_PID command in a while loop> And loop through it until the process exists. This is one of the approach you could try..
Code:
BG_PID=$!
while [ ... ]
do
        ps -p $BG_PID 
done
echo $(basename $file) >> log
