If you have to run a script that processes data for a particular file for a particular day, i.e. your file is on hadoop with the date in the path, like this:
/path/to/my/data/2013/09/23/*
And you have multiple days to process, don’t run them manually. Use a for loop instead:
for day in {19..22}
do
./my_script.sh 2013/09/$day
done
