Create a bootable USB stick with terminal UI display
Building It
As always, the listings for this article are available for download from the Linux Magazine web server [2]. Once you have the three files – cpchunks.go
(Listing 1), drive.go
(Listing 2), and isoflash.go
(Listing 3) – in one directory, the first two lines of Listing 4 create the isoflash
binary. Then, you need to call the program with sudo
to have write permissions for the USB stick (last line).
Listing 4
Calling the Binary
$ go mod init isoflash $ go build $ sudo ./isoflash ubuntu.iso
Right after the program starts, it immediately instructs the user to plug in the USB stick (Figure 1). As soon as it finds the newly plugged in device, it starts to copy the data after confirmation from the user (Figure 2). It uses a progress bar to show the current state of affairs (Figure 3). After finishing, the UI reports that the action was successful (Figure 4). All done!
