Would be good if i explained what i was trying to achieve, wouldn't it. Basically I'm getting together the commands needed to copy files off of a USB stick, write an ISO to it, recreate a partition and copy the files back to it. I've ended up with this method because GUI based programs write an ISO9660 partition to the entire 64GB drive leaving it unusable as a storage medium, whereas dd left me with 60 odd GB of unpartitioned space afterwards. Because i don't want to do it all by hand and risk forgetting the commands when i need to update the live USB/install medium in years to come i though making script to update the USB when needs be would be better. Not even when the file ends with an ".iso" extension, like they do? Either way I've also tried simply using "manjaro*" (without the quotations) and it still claims the file " manjaro-kde-18.1.1-191015-linux53.iso" that's in the directory it's being run from and it can find when using the full filename isn't there.
