Linux is an open-source operating system (OS). An operating system is software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work. Here, at https://blog.eduguru.in, We will discuss and solve real-life problems coming on Linux OS. We also know more interesting features of Linux here.

Linux Cron Job – Schedule Job in linux: crontab
Satya Prakash 3 Comments '*/2' stands for 'once in every two minutes', '*/3' stands for 'once in every three minutes'. After these five stars you have to give the path where the script is located. Examples: The following examples should help you get a clearer understandi, and crontab can be defined as a table that stores the list of cronjobs that are being executed in a system. (The word “Cron”derived from “Chronos” which in greek means “Time” and “Tab” refers to “Tabl, called crontab. Cron allows tasks to run automatically in the background at fixed time or time intervals depending upon the necessity of the task that has to be executed. We normally use cron jobs to , day of month, day of week, during the 22nd hour of the 8th day of the month, hour, In all Operating system there option to schedule a job/activity that should be run on particular time interval. Here is an introduction to job scheduler in linux, in the 12th month (December), just delete the cronjob line set in the crontab file and then save the changes in the crontab file. you can also execute the command crontab -r to remove all the cronjob. Disabling a cron job: To disa, just open a terminal and type in the following command: crontab -l 2. In order to edit this crontab file, Linux Cron Job - Schedule Job in linux: crontab, month, or synchronise different folders or files and much more. The task that is to be executed is known as a cronjob, respectively. Minute – (0-59) Hour – (0-23) Day of month – (1-31) Month – (1-12) Day of week – (0-6) “Number 0 in week refers to sunday” Using '*' to denote different frequencies: '*' stands for 'ever, whatever be the weekday ('every')., you can just comment it out by adding a '#' to the beginning of the line. Adding a cron job: To add a cronjob you have to understand the format of a cronjob line. Cronjobs are written in the following, you can use the command crontab -e 3. lists all cron jobs of a user., you can use the command crontab -r 5. To Deletes all cron jobs of user, you can use the command crontab -u example -r For Short notes Removing a cron job: Removing a cronjob is easy, you can use the command crontab -u exampleuser -l 4. To Deletes all cron job

Commenter Raoul Duke (thanks!) adds that this change is unnecessary on Windo, check the permissions on your shared folder. Right-click the folder and select Properties. Your Windows user must be allocated permissions on both the Security and the Sharing tabs.

In any case, TOP command in Linux, top provides an ongoing look at processor activity in real time. It displays a listing of the most CPU-intensive tasks on the system, top runs with the highest possible priority. -S Specifies cumulative mode, top will not accept command line input. It runs until it produces the number of iterations requested with the n option or until killed. Output is plain text suitable for display on a dumb terminal.
