Issue
I have a small script, which is called daily by crontab using the following command:
/homedir/MyScript &> some_log.log
The problem with this method is that some_log.log is only created after MyScript finishes. I would like to flush the output of the program into the file while it's running so I could do things like
tail -f some_log.log
and keep track of the progress, etc.
Solution
bash itself will never actually write any output to your log file. Instead, the commands it invokes as part of the script will each individually write output and flush whenever they feel like it. So your question is really how to force the commands within the bash script to flush, and that depends on what they are.
