Sometimes it’s useful to make sure a Bash shell script doesn’t run too frequently. Here’s a neat way to set a time limit that must expire before the script can run again.

Depending on what it’s doing and which other processes it may launch, a Bash script can consume as much RAM and CPU time as any other resource-hungry process. It can be useful to limit how frequently such a script can be launched.Enforcing a period of respite between each run of a heavyweight script stops it from hogging resources. Computationally expensive scripts can monopolize computers to the point where other users experience a drop in performance.

In extreme cases, if the script causes a lot of disk churn, for example, it can even hasten the demise of your hardware.Of course, engineering a scheme that limits how soon you can relaunch a script adds code to your script, and gives it one more thing to do. That might sound counterproductive, but if the checks are lightweight and fast, their tiny overheads are far outweighed by their resource savings.

The robocopy (robust file and folder copy) is a command line tool available in Windows that copies files from one place to another. It can copy between directories on the same drive, or between devices like USB sticks and portable disks, and to network locations.

When to Use the Robocopy Command

The robocopy command is perfect for automating your workflows. If you regularly have to copy files between the same locations, you can set up a script to do it all for you rather than having to perform the task manually.It’s particularly useful for performing backup tasks, with the added advantage that you won’t have to remember to perform the backup, improving the reliability of your backup practices. You can use robocopy to regularly back up your files to an external drive, or to cloud storage.

If you need to make deep changes to Windows 10 or Windows 11, you sometimes need to open Group Policy Editor, a tool that ships with Windows Pro and Enterprise editions only.

What Is the Group Policy Editor?

It only ships with Windows 10 or Windows 11 Pro or Enterprise editions.

If you’re not sure which edition of Windows you have, it’s easy to find out. Open Settings, navigate to System > About, and you’ll see it listed under Edition.There are several ways to open Group Policy Editor in Windows 10 and Windows 11, so we’ll cover a handful of major ways to do it below.

The gpasswd command lets you administer groups on Linux. Group passwords don’t get used a lot in part because of the security risk they pose: multiple people sharing a password increases the opportunity for accidental or malicious exposure. Any member of the group can add or remove members, controlling the group access, which could easily get out of hand. There are a few ways to overcome this problem. You can avoid using group passwords when possible and use alternative mechanisms such as sudoers or access control lists. You can also limit access to the group passwords using privilege control so that only authorized members can do any operations.
