How do I change the Owner of a USB drive from "kev" to root? For the owner of a USB drive partition to be anything other than root, it must be currently mounted by the user "kev". From a Terminal session, find the drive by typing "dmesg". This will bring up a long list of everything that was started at boot time. If the drive is not listed, it is unmounted. Mount it using Gnome, and run "dmesg" again. This time, it will include something like "/dev/sdc1" Change directory to the /media/ directory. Type "chown root:root usbdrivewhatever", where usbdrivewhatever is the folder given to the drive's partition. How to list files in sub-directories, "ls -R .jump" doesn't work? Using ls -R .jump would only show any *.jump files in the current directory. To see all of the *.jump files in any forward sub-directory from your current directory, use ls -R */*.jump To see all of the .j* files in any forward sub-directory from your current directory, use ls -R */*.j* This would not show any *.j* file in your current directory. This is because the -R option recurses sub-directories, not the current one. To see all of the .j* files in any forward sub-directory beginning with "n" from your current directory, use ls -R n*/*.j* This would show files such as notes/wow.jump. It would not show any *.j* file in your current directory. You can do complex wildcard searches such as ls -R *n*/*a*.*f* This would show files only in sub-directories named with the letter "n" in them, that have the letter "a" in the first part, and the letter "f" in the extension (filetype). How do I check a FAT32 partition and get details, as fsck can't handle it? "fsck.vfat /dev/sda1" is the same as "dosfskck /dev/sda1" You need to be root, so type, "sudo dosfsck -n -v /dev/sda1" The "-n" option will do nothing to the partition, even if it has unmarked bad blocks or a bad File Allocation Table. "dosfsck --help" gives more options. I do not recommend automatically repairing file systems. To repair interactively, use the "-r" option. The "-v" option gives verbose details about cluster and sector sizes. The "-V" option verifies everything after fixing. The "-w" option writes changes to disk immediately, which saves worrying about write-behind caching. How can I be sure all data is written to a drive, e.g. a USB flash drive or memory stick? From Terminal, type sync This flushes write buffers, and updates either the super block or File Allocation Table. If I try to copy data back onto a new FAT32 partition it runs out of room. This is because data stored in other filesystems can be more efficiently stored than FAT32 does. Cluster sizes can be changed in FAT32, but it would be better to put some of the data elsewhere. How do I add fonts (TTF)? These In Firefox, where is the Import option in the File menu? In Ubuntu's Firefox, bookmark options are all within the "Bookmarks" menu's "Organise bookmarks" option. Where does it file bookmarks so I can add Favorites.htm manually? Within the "Organise bookmarks" window, there is an "Import and Backup" menu that will do all of this. How do I rename all directories starting with the text string "project " to not have this text? I tried mv "project *" "*". but got the error "mv: cannot stat `project *': No such file or directory". ----------------------------------------------------------------------------------------
