Your statement.... left me confused so I just bypassed it (but kept it and Tomas' in mind). Five seconds later I entered that full command into a search engine. For others likewise confused but less bold about speaking up, this is one of the article/inquiry titles the search engine pulled up: "How do I clean or disable the memory cache?" Ahhhh... The potential to (accidentally, even) *disable*.. That's what the two responses must mean in this "solved" thread. Definitely not what I personally would be wanting to do with anything memory related. Thank you *SO MUCH* for highlighting that particular potential outcome. That's a BIGGIE. In fact it comes to mind to very unhumbly suggest that some of us keep a mental tickle file on it as one checkpoint to ask users with (computer) memory issues. Just make sure they didn't accidentally *disable* something while following [destructions] out on the Internet. PS The 30 browser tabs open.. I wish! This thread has been of interest because I'm facing needing a way to cleanse memory out without rebooting**. The no-brainer in my case is "a few" tabs too many opened in Iceweasel. I've been "cleansing" those out the last couple days.. That project's moving right along. The count's currently down to.. 4 open windows with ~350 tabs open between them on 1GB memory. Again. lol =) Cindy :) ** I'm trying to mentally work through a BAD #1 critical Debian bug without rebooting. Rebooting means losing, breaking the virtual train of thought to this point this second. For people in my cognitive (disability type) Shoes, it represents a major loss. It's why we get stubborn about things like not rebooting sometimes. :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with duct tape *
