Easy way to attach notes to commands you've used

[shedyed]

You're at the command prompt. Hit the up_arrow to bring up the last command you've just discovered e.g. htop to see all jobs in the system.
At the prompt, press the up_arrow.
When you see htop, insert echo followed by a space and single quote. Press END to type the end quote, followed by > READMENOW.TXT

READMENOW.TXT can be a different name; it will be a text file with notes about recent commands. You can use a different name, or lowercase, for that matter. Remember to keep it unique, that's all.
For any succeeding commands, you just hit the UP_Arrow, enclose in quotes, but the > is now a double:
echo 'date +%A returns the day' >> READMENOW.TXT

Continue adding notes this way. When it's time to use a new computer, you can move the file over or copy it to a thumb drive, email it, whatever. On the new computer, you can learn about a text editor called vim or emacs or jstar

I like that idea!
