Suppose you worked on your Linux system for 2 hours. Now, tell me how much memory is left on your system?

Type free -h in the terminal, and it will show how much memory is left on your system. After typing the command, the memory is shown in two parts:

1. RAM → The system’s main memory is displayed, showing how much is available in bytes or gigabytes.

2. Swap → Temporary memory is shown, showing how much memory has been used, also in bytes or gigabytes.
