Hmm. Same here. Just upgraded to HF8 a couple of hours ago and the typo is still in the "tmsh run sys crypto check-cert". Could be a remnant from an old version. I've seen some funny stuff hiding after upgrade. Our box was origanally in the 9.x branch when first bought, Then 10.x, and finally 11.x before going into production. So we found some scripts that still used Korn shell and similar stuff. But well.. No biggie, just fix the typo so it matches your output :)
