[Bug 577232] Re: swapon/swapoff not as described in man page

[Daniel Richard G.]

Firas, I see what you mean. The lack of mention of long options in the
usage summary and man-page synopsis threw me off the trail.

My use case was to pass in a laundry list of devices on the command
line, and have swapoff(8) do its thing while ignoring invalid-device
errors (rather than stick a "2>/dev/null || true" afterward), so the
clarification of what -e/--ifexists does is appreciated as well.

I'll change this to a wishlist-type bug, requesting more clarity on the
man page (flesh out description of -e/--ifexists to what you wrote) and
usage summary (mention long options).
