Write a one-liner to find files larger than 100MB.

I like to use that one liner when you deal with storage problems on servers you manage. You run it to locate oversized items taking up space. It helps you free up room without guessing. But you must specify the path right or it searches everywhere. Then the output shows you the culprits clearly. Also you combine it with other steps for better results. Perhaps you sort the list by size next. Now you see patterns in file growth over time. I remember cases where logs bloated everything. You learn to act before issues hit hard. Or you check permissions first so nothing breaks during review. Maybe you test on a small folder to see how it behaves. Then you apply it across bigger drives with care. I find it saves hours compared to manual checks you do by hand. Also it reveals hidden temp files users forget about often. You gain insight into what eats resources daily. But watch for false positives from system files you should leave alone. Now you tie this into routine maintenance you schedule weekly.
I recall moments when disks filled suddenly and you needed quick answers fast. You poke at the results to decide what moves or deletes. It shows sizes in readable form so you grasp the scale easy. And you avoid bigger crashes by catching trends early on. Perhaps you log the findings for reports you send to bosses. Then you compare runs over days to track changes you notice. I use it on client machines too when complaints come in about slowness. You explain to juniors like you how it pinpoints problems without fancy tools. Or you extend the idea to network shares if access allows it. Maybe you combine with alerts you set up for future warnings. Now you understand why space audits matter in admin roles you chase. Also it teaches you about file system limits that surprise people later. You build better habits from these simple checks you repeat often. But always back up first in case something important hides there. I see it come up in job talks about real world troubleshooting you face.
You explore drive health by hunting those big files that linger. It uncovers duplicates you never knew existed before. And you clean them to boost speed on older hardware you maintain. Perhaps you script follow ups that act on the list you get. Then you monitor growth in user folders with repeated uses. I like how it keeps things practical without extra software installs. You share tips like this with teams to speed up everyone involved. Or you adapt it for different operating setups you encounter daily. Maybe you focus on certain extensions that bloat most often. Now you connect it to quota enforcement you enforce on servers. Also it helps during migrations when you move data around. You avoid surprises by knowing the layout upfront always. But test commands in safe spots to prevent mistakes you regret. I think these skills set you apart in interviews for admin spots.
