Shell scripting is a way of writing custom command line scripts that run in a Linux or Unix environment, and perform system operations either on demand or on a set schedule. The OS itself depends on many different types of shell scripts to automate certain system tasks, check for issues, and load resources. Shell scripts can also be used to automate all kinds of things inside the environment for security, disaster recovery, and system control purposes. Read below to learn more about just a few of the things we can do with custom shell scripts.
Automating system backups
There is no question that system backups are crucial for any business to secure its IT data. Hard drives fail, systems crash, and security intrusions can happen. It’s in these situations that it is critical for a business to have backups securely off-site, and a recovery plan in place. We have the experience to not only automate your backups but also assess your current disaster recovery plan so you can sleep well knowing that you are in complete control of your IT.
Automated resource monitoring
It’s very common for systems to see spikes in resources when an application is experiencing growth or change. If the user sessions spike higher than normal, the RAM and CPU can become overloaded causing slow page responses or no response at all. If the file system becomes too full of images, log files, or other session data, the OS or services running on the OS can crash, making your server and applications non-responsive. We have even seen cases where a backup server becomes full, causing backups to build up locally until the hard drive fills up and crashes the system. The good news is that all of this can be prevented with proper system monitoring. Running scheduled tasks on a regular basis to check for critical system resource thresholds can prevent these problems from occurring in the first place by alerting the proper system admins. Don’t wait until your system crashes to take reactive measure. Instead, give us a call and be proactive about your system administration processes.
