swaptop
htop-style view of which processes are using swap, and how. Linux only.
The header splits swap in use into memory owned by processes (green), swap
cache (yellow: pages that are in RAM and still hold a swap slot, so
reserved rather than really swapped out) and tmpfs/shm (magenta). zswap and
zram figures appear when present. Each process shows its SWAP, proportional
SWPPSS, DELTA since the last refresh, RSS and how much of it is in swap;
Enter breaks a process down by mapping (heap, stacks, libraries, files).
Actions, each confirmed first: swap a process back in (i), page a process
out (o, process_madvise, Linux 5.10+), flush every swap device with
swapoff+swapon (F), send a signal (k). Search (/), sort (s), tree
view (t), zero-swap toggle (z), full command line (c), help (h). Settings
persist in ~/.config/swaptop/config. See man swaptop.
Run it as root to see every process and use the actions:
sudo swaptop
