As is known, the “.Iso” is usually used to describe ISO images, ie files that alone the entire contents of a computer readable media such as a CD Rom or a DVD ISO file can be used without any conversion through special programs called emulators or restored to original state for burning.
In Linux, the content conversion of optical media in ISO image can be done through a simple command:
<span onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left;">dd if=/dev/cdrom of=file.iso</span> dd if = / dev / cdrom of = file.iso</span>
which also has its educational equivalent:
<span onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left;">cat /dev/cdrom > file.iso</span> cat / dev / cdrom> file.iso</span>
In case you want to create ISO image to a directory, the command to be used will be different but equally simple:
<span onmouseover="_tipon(this)" onmouseout="_tipoff()"><span class="google-src-text" style="direction: ltr; text-align: left;">mkisofs -r -o file.iso /directory</span> mkisofs-r-o file.iso / directory</span>
The name for the ISO file can be chosen arbitrarily.
