I'm just confused abo= ut where the 12G went.=20 Well, commands like df and du can only estimate about how much disk space there really is used. du may say a file is only 10 bytes, but it probably takes up at least 1k of space. A 900 byte file probably also takes up 1k so it's not a multiplier, but rounding. My favorite way to find out how much diskspace a drive has left is to do cat /dev/zero > /path/to/test/partition/file, then do a ls -l on the file to see how much space it takes up. Only do this if filling up the partiton won't interfere with anyone or any thing else. You can also do a df -h once full just for kicks. Lastly, a non-root user can only fill a partition to 95% by default so, unless you run it as root, u'll still have 5% free space when done. >=20 > Anyone have any helpful pointers to help me understand?=20 >=20 > Also, what's the ".snap/" directory for?=20 >=20 > Thanks so much! > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.o= rg" --=20 I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering. NT is the path to the darkside. Powerful Unix is.
