I have a very basic mp3 player with only 128 MB memory. I mostly listen to podcasts which are automatically downloaded by Amarok into the folder ~/.kde/share/apps/amarok/podcasts/data. In order to fit many of them to the limited memory and to have them available from anywhere, I have been writing a script that automatically downsamples them as they arrive and puts them online to my web server. The script is executed hourly by the crontab. The relevant files look like this:
Creating and mounting iso images under linux is very easy.
Creating:
dd if=/dev/cdrom of=filename.isoMounting:
sudo mount -o loop -t iso9660 filename.iso /mnt/isoThe file endings iso, raw and cdr denote all iso files. Image files with the bin/cue ending, however, are not iso files. You can convert them into iso files with bchunk. bchunk needs the cue file to do this! Allthough some non-Linux burning applications (e.g. Toast Titanium for MacOS) can handle (burn and convert) the bin file without the cue file.
