When I input that string into a computer running Debian, it produces an
error message:

The iso file is not a command that you run on a Debian system. If you have cd'd to the present working directory that the iso is located in you still have to use "./"  ./ tells the OS that the file is located in the present working directory pwd.

A Debian Installer "isohybrid" file is compatible with optical media
(e.g. CD-R, DVD-R, or BD-R) and with USB flash drives.


If you wish to create Debian installation media, start by downloading a
Debian Installer isohybrid file:

https://www.debian.org/distrib/


Different computer architectures require different Debian Installer
isohybrid files.  Here is the one for 64-bit "Windows PC's":

https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-12.6.0-amd64-netinst.iso


Burning the Debian Installer isohybrid file onto an optical disc was
easy when most PC's came with Windows, CD-RW drives, and burning
software (e.g. Nero).  Today, Rufus seems to be a popular Windows
application for copying ISO images to USB flash drives (untested):

If you have a friend with Linux or BSD, they can use the dd(1) command
to copy the Debian Installer isohybrid file to a USB flash drive:

https://wiki.debian.org/DebianInstaller/CreateUSBMedia


Alternatively, you can purchase Debian Installer media from vendors:

https://www.debian.org/CD/vendors/


Be very careful if you boot the Debian Installer on a computer that
already has another operating system installed.  Using the Debian
Installer Rescue Shell can be useful for troubleshooting, but requires
advanced knowledge and skills.  Creating and maintaining a "dual boot"
system requires even more knowledge and skills.


I suggest obtaining a used 64-bit "Windows PC" and using it only for Debian.


You can skip the installation media entirely by installing a hypervisor
on your computer, creating a virtual machine (VM), loading the Debian
Installer isohybrid file into the virtual optical disk drive, booting
the VM, and installing Debian.  I like VirtualBox:

https://www.virtualbox.org/


I recommend that you buy and read "Learning the Unix Operating System"
by Peek, et al:

https://www.amazon.com/_/dp/0596002610


Then "UNIX and Linux System Administration Handbook" by Nemeth, et al:

https://www.amazon.com/dp/0134277554
