I don’t just mean a wrench, unless thats it for you. I mean any tool you regularly use for work that you consider your most important. If you’re a software person name whatever digital tool you guys use. Whatever the career everyone uses tools I dont care if they are digital, verbal, physical or psychological. For me its honestly probably a flashlight, before I use any tools I’m always investigating with my flashlight or using a laser to trace lines.
I do sys admin/engineering work in a Windows environment. PowerShell is what got me this job, and together with my programming experience allows me to keep up with my seniors who have been in their positions for a decade or more.
It also helps us all make a good team. They have the knowledge and experience advantage (though I’m catching up), I have the skills to figure out how to implement/automate the plans in a way that doesn’t involve days of mind numbing manual actions.
PowerShell is absolutely required to admin Windows. You don’t have to be expert level, but you should be able to eventually get a script out that does the job.
