posted message: GNU/Linux Tip of the Day: Using the `watch` utility will allow you to run a command at a set interval. For instance, say you need to check the status of a process and you were using `ps -aux`. You could do `watch -n 2 'ps -aux | grep PID'` and the grep you issued would repeat every 2 seconds since we defined a 2 second interval with -n.
posted message: GNU/Linux Tip of the day: using the nohup utility followed by a command and the & will allow you to run a script immune to any hangups as a background process. Example: `nohup php script.php &` will run the script.php file as a background process while making sure there are no interruptions.

posted message: Apart from the courses, I want to invite everyone to post what they would like to learn. We can have group discussions, regarding the topic you choose. If I get enough votes for a video on that topic, then I will also make a video walking you whatever we voted on.
posted message: Sorry I wasn't able to post a new video this weekend. I will work on making some this coming week to make up for it. I have created a task in the mean time for everyone to do some research.
posted message: Only a few videos left to post, and then we will have 1 last exam which will allow you to get your level 1 certification. Certifications will be issued using the name provided in the Courses site. You will receive a email with a PDF version of the certification after you pass the course. If you would like a hard copy please get in contact with me for more details. A new course will be open then after for the level 2 which will cover more advance topics as well as security. There will be 3 Levels in total to the GNU Linux certifications, where the 3rd one will be the highest you can achieve through P2PU and DevBlog Courses.
posted message: Cool GNU Linux Tip for Today: Configure NTP on your system to synchronize your time. There are only 4 steps to do this. First install ntp "yum -y install ntp". Second synchronize NTP to a defined server "ntpdate pool.ntp.org". Next start the ntpd service "service ntpd start". Lastly, make it so ntpd starts after each reboot "chkconfig ntpd on". You can find a tutorial here: http://www.devblog.co/configure-ntp-network-time-protocol-to-synchronize-your-system-clock/
posted message: Cool GNU Linux Tip for Today: Customize your VIM editor by adding a tree explorer. The NERD tree allows you to explore your filesystem and to open files and directories. It presents the filesystem to you in the form of a tree which you
manipulate with the keyboard and/or mouse. It also allows you to perform
simple filesystem operations. To install: Put NERD_tree.vim in ~/.vim/plugin and NERD_tree.txt in ~/.vim/doc. For more information click here: http://bit.ly/s3US
posted message: Cool GNU Linux Tip for today: Say you want to view the contents for the bottom of a file live to see changes or additions. You can use the tail utility along with the -f flag.
For instance, As you run a PHP script you want to see if anything gets added to the php error log. You could use `tail -f /path/to/php_error_log`
