Ccommand line application or script which parses a cron string and expands each field to show the times at which it will run.

You should only consider the standard cron format with five time fields (minute, hour, day of month, month, and day of week) plus a command, scrip doesn't handle time strings such as "@yearly". The input must be on a single line.

~$ python3 cronjob.py "*/15 0 1,15 * 1-5 /usr/bin/find"

The output is formatted as a table with the field name taking the first 14 columns and the times as a space-separated list following it. For example, the following input argument:

python3 cronjob.py */15 0 1,15 * 1-5 /usr/bin/find

Yields the following output:

minute        0 15 30 45
hour          0
day of month  1 15
month         1 2 3 4 5 6 7 8 9 10 11 12
day of week   1 2 3 4 5
command       /usr/bin/find
