Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".
The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!
In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.
So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.
Your question(s) could easily be answered by searching the Internet with Google. Google is your friend
Per forum rules, and the benefit of all users, please search the network and the forums before posting a question.
