# 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:
|
|
|
|
```sh
|
|
sudo swaptop
|
|
```
|
|
|
|
