frei (FREe Improved) is a modern replacement for the free command.
free shows your memory usage on Unix-based systems. frei obtains memory data from /proc/meminfo and represents it in a colored bar chart using the same color-coding for as htop.
“Free” (MemFree in /proc/meminfo) reports just the amount of memory that is currently not in use. “Available” (MemAvailable in /proc/meminfo), on the other side, is a more sophisticated estimation of how much memory is available for starting new applications, without swapping. It takes into account the page size and how much of reclaimable memory can actually be reclaimed.
Key Features
- -h flag shows human-readable numbers
- -table flag prints a table with numbers in addition to the chart.
