  • I am new to linux, and I was trying to figure out why I could not sudo with my username in Fedora 10. This command, when run as root, will add a line to the sudoers file allowing the loginname supplied to sudo. The above line will require a password when you sudo, if you wish to sudo without password, use: echo 'loginname ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers instead. you have to run this command as su, and this is just an easier way of using visudo, just adds it right from the terminal.

    echo 'loginname ALL=(ALL) ALL' >> /etc/sudoers

convert vdi to vmdk (virtualbox hard disk conversion to vmware hard disk format)
Converts a .vdi file to a .vmdk file for use in a vmware virtual machine. The benefit: using this method actually works. There are others out there that claim to give you a working .vmdk by simply using the qemu-img command alone. Doing that only results in pain for you because the .vmdk file will be created with no errors, but it won't boot either. Be advised that these conversions are very disk-intensive by nature; you are probably dealing with disk images several gigabytes in size. Once finished, the process of using the new .vmdk file is left as an exercise to the reader.

...can do similar w/ tar, dd, xfsdump, e2fsdump, etc.

Go (cd) directly into a new temp folder
