If you have one too many SSL certificates to manage, there is one nifty program made with Bash that can determine a certificate’s validity.

SSL Certificate Expiration Check can do that for you and send the results to email. The program’s “send to email” feature allows the user to simply add it to cron to check the certificates and send an alert to the administrator if any certificate (from file or website) falls below the set expiration date.

Tip: How to Use watch Command

I have never known that there is a command in Linux called watch. Basically, watch runs a program in a period of time, and displaying the output in real time.

watch command syntax is very simple. One typical use of the command watch is running it with traceroute. This is one example:

watch 'traceroute google.com'

This will run the traceroute command, display the output and when it is done, it repeats the process again.

Here a couple more examples of the watch command:

watch -n 10 free -m

This command will run the command free in ten-second intervals, and display the output.

watch -n 3 'cat /proc/interrupts'

This command will display the interrupts in 3-second intervals.

WazzupManila.com is the site that you should visit if you are looking for a place to chill in Manila Philippines. They also have classified ads of many different things from apartments, hotels, and resorts (and you can place ads for free) or connect with someone through their forum.

What they do have that is really exciting is they are giving away free free movie for two. This promo is run in conjunction with Magic 88.9.fm, my favorite radio station in Manila.
