using dd writing iso file to usb drive

[Kyle]

If the iso file you are writing is the only file in the directory, you 
should be able to have it filled in by pressing the tab key immediately 
after if=. So dd if=<tab> would fill in the filename, unless you do have 
more than one file, in which case, you can tab again and get the list. 
If you are typing a letter or two and the tab completion isn't working, 
my best guess is that the filename is capitalized and you're typing a 
lowercase letter, or else the filename is lowercase and you're typing a 
capital letter, in which case, Bash won't correct you. That said, 
usb-creator-gtk is probably your best option, as it allows you to choose 
exactly the file and device you want.
