Suppose you needed to run a cron job that ran only on the first x-day of the month. It’s easy to create a cron that runs every x-day, but how would you specify the first? The solution is pretty nifty. Simply create a cron that would run a job every x-day, but then have that cron execute a script that evaluates whether it is indeed the first occurrence of that day in a given month. If yes, it will execute your script. If no, it will do nothing.

Example for running a cron the first Wednesday of every month at midnight:
0 0 * * 3 [ "$(date '+\%d')" -le 7 ] && /usr/local/bin/myscript.sh > /dev/null

The cron will indeed run every Wednesday, but the conditional statement will only execute myscript.sh if the current day of the month is less than or equal to seven. Perfect!

The Windows Version of APG is Here!

APG generates passwords with two, three, or four random common dictionary words. It displays length and approximate bits of entropy. These types of passwords are among the most difficult to crack during brute-force attacks. Mathematicians have proven that the length of the password is often more important than the complexity. For example, if a person had the password “$3cureP@ssword!” versus a password based on four common yet unrelated dictionary words such as “supermarket-gallery-hang-voyage”, the latter would take far longer to crack during a brute-force attack. Additionally, people who are forced to use complex passwords often write them down. However, a password based on four common English words is much easier for someone to remember, and at the same time secure.
