7 AI-Built Cheat Sheets Every IT Pro Should Keep

4:47 p.m. You are at mid-fix. The command is on the tip of your tongue.

You open a tab. You type the same search you typed in March.

You find the flag. You run it. It works. You save it nowhere. Next quarter, you will do this again.

"Keeping a notes file" is decent advice. But it is now 3,000 lines, unsorted, and half of it points at servers that no longer exist.

Notes rot because they are written once and never edited. Your environment keeps moving. The file does not.

AI does not fix this by being brilliant. It fixes it by doing the chores you skip: sorting, rewording, flagging what looks stale. You still decide what is true. That division of labor is the whole point.

Clever is loud. Current is quiet. The quiet ones keep paying.

This is my read, not a promise. I left out AI-written scripts and full automation. They require more trust than a cheat sheet deserves. The list below is ranked by speed of payoff: this week, this month, this quarter.

$ Tier 1: The Fast Starters

Payoff: this week. Trade-off: narrow, and you will outgrow them.

Tier 1 — This Week

01. "Googled It Twice" Sheet

A short list of commands you have looked up more than once, each with a plain-English note and a "use this when…" line so you find it by situation, not syntax.

Start with: Scrub your last 200 lines of shell history, paste them into AI, and ask it to group and explain them.

Caution: shell history can hold passwords and tokens. Scrub before you paste.

02. The Error-to-Fix Lookup

A two-column table: exact error text on the left, the fix that actually worked on the right. Character-for-character matching so Ctrl+F lands at 2 a.m.

Start with: After your next fix, paste the error and solution into AI and ask for a one-line entry.

Watch out: AI loves to tidy error text, which quietly breaks your ability to search it.

03. The Flag Decoder

Plain-English breakdowns of the gnarly commands you paste without reading: tar, rsync, find, openssl. Every flag explained, plus "what breaks if I get this wrong."

Start with: Pick one command you run on autopilot and ask AI to explain every flag.

Watch out: AI will state a wrong flag with total confidence. Test on a throwaway machine first.

$ Tier 2: The Skill-Based Middle

Tier 2 — This Month Payoff: within a month. Trade-off: you have to feed it real details from your environment.

04. Your-Environment Sheet

Generic commands rewritten with your actual paths, naming patterns, and server roles. The value is not in the commands. It is in writing your conventions down once, in one place, instead of keeping them in everyone's head.

Start with: Take three generic commands, add a sanitized version of your naming scheme, and ask AI to rewrite them for your setup.

caution: real hostnames, IPs, and account names do not belong in a public AI tool. Use placeholders.

05. The Symptom-to-Checks Tree

A short "if you see this, check that" list for common problems. Cheapest, fastest check first; scary, disruptive check last. Built for 3 a.m. brains.

Start with: Write down the last problem that took too long, then ask AI to turn your steps into ordered checks.

Watch out: AI will add plausible checks you never ran. Delete anything you have not verified.

$ Tier 3: The Longer Builds

Tier 3 — This Quarter Payoff: over a quarter. Trade-off: slow start, and they need upkeep.

06. Runbooks from Your Own Tickets

Step-by-step procedures built from how you actually resolved past tickets. The real test: hand it to a teammate cold, watch where they get stuck, and fix those spots.

Start with: Pick one recurring ticket type and paste three anonymized resolutions into AI to draft a procedure.

Watch out: ticket text hides names and internal details. Anonymize first.

07. The Monthly Review Loop

This is not a document. It is a ten-minute monthly habit where AI reviews your sheets and flags stale, duplicate, or contradictory entries. Add a "last checked" date to every entry so you can see what is aging.

Start with: Paste one sheet into AI and ask what looks outdated, repeated, or missing an example.

Watch out: reviews drift into busywork, so cap it at ten minutes or it quietly dies.

The other six are files. This one is a habit, and habits outlast tools, jobs, and whatever AI looks like in three years.

How to Actually Use This List

Do not start with all seven. You will build three half-sheets and trust none of them.

Start with one. Add its natural partner once it feels easy.

• The "Googled it twice" sheet, then the flag decoder.
• The error lookup, then the symptom tree.
• The environment sheet, then runbooks.

Then add the review loop and leave it running.

"Living" does not mean automatic.

Today, my cheat sheets are the first place I look, not the last. They are messy, personal, and constantly evolving, which is exactly why they work better than any wiki. Dump your history. Let AI organize it.
