💡Quick Linux Tip #22

You accidentally deleted something and want to know what was removed recently.

Run:

find ~/ -type f -mtime -1

This shows files that were modified in the last day.

While it won't recover deleted files, it can help you identify recent changes and missing files.

It's often useful when troubleshooting user mistakes.

The reason why large asteroids don't fall to Earth every day and cause disasters is because Jupiter's gravity attracts asteroids and protects the inner planets.

An atom is extremely small—so small that millions of them can fit across the width of a human hair. The diameter of a typical atom is about 0.1 nanometers, which is one ten-millionth of a millimeter. Atoms are made mostly of empty space, with a tiny, dense nucleus at the center surrounded by electrons. Despite their size, atoms are the basic building blocks of everything around us.
