Simple Utility for viewing/extracting contents in ISO files

Burgin · 06-01-2004, 09:50 AM

Sounds like a stupid question but I can´t seem to find what I´m looking for by googling.

I just want see and extract what´s inside an ISO image file without burning a CD. I´d like a simple tool that runs on Linux OR Windows.

You´d think there would be a plugin for Winzip or the KDE Archiving tool that would let you do this.

I think rar can extract the contents of an iso, and you could always simply Mount the image and access what's inside the iso without a problem

. Needless to say, if you extract the contents of the iso with rar, it will no longer be a bootable image...

As Windows lacks the "mount" command, you could use a third part program as Daemon Tools to mount iso images... If you have good free space on your HD it's always good practice to convert a CD (specially games) into iso, then "mount" them and run everything from the HD for better performance, plus you don't need to look after the CD's all the time you want to play a game

Ah, you can just mount it! I should have thought of that. No need to install anything special.

Thanks Xander...

mount -o loop -t iso9660 iso_name.iso /mnt/mount_point_desired

Thanks guys, now the next logical step might be to do all this on the fly with a script that takes the name of an ISO file as an arg and then creates a subdir under under /mnt of the same name and then runs that ¨mount -o loop....¨

but I haven´t quite got that far yet in my studies.

Put this script in your ~/bin directory as 'whatson':

Code:

#!/bin/bash

sdir=${1:-cdrom}


if [ $sdir == cdimg ]; then
    if [ `id -u` != '0' ]; then
	export WHATSON_CDIMG_FILE=$2
	echo "You must become root to mount an image"
	exec su -c "$0 cdimg"
    fi
    file=$2
    [ -z $file ] && file=$WHATSON_CDIMG_FILE
    dir=/mnt/tmp-whatson-$$
    mkdir $dir
    mount="mount -t iso9660 -o loop $file $dir"
    remove=1
else
    dir=/mnt/$sdir
    eject=1
    mount="mount $dir"
    
fi
echo "$mount"
if [ x$TERM == xxterm ]; then
    PROMPT_COMMAND='echo -ne "\033]0;[whatson '$sdir'] ${USER}@${HOSTNAME%%.*}:${PWD/#$HOME/~}\007"'
    export PROMPT_COMMAND
fi
[ -z $eject ] || eject -t $dir &> /dev/null
if $mount; then
    cd $dir
    echo 'Contents:'
    ls --color=tty -Fhp 
    echo 'Starting subshell...'
    bash
    cd ~
    umount $dir
fi
[ -z $eject ] || eject $dir &> /dev/null
[ -z $remove ] || rm -rf $dir

This is a script I first wrote a long time ago to help me sort out a bunch of unlabeled CDRs I had laying around.

To use it for physical media (cds, floppies, etc.), run it as 'whatson [directory]' where directory is the subdirectory of /mnt where the medium is mounted (e.g. floppy for /mnt/floppy, cdrom for /mnt/cdrom). If the directory is omitted, it defaults to 'cdrom'. It will automatically close the tray (on cdroms and dvdroms), mount it, start a shell, and will unmount and eject on exit.

For images, use the command 'whatson cdimg image-file' where image-file is the file name of the image to be mounted. If you are not running as root, the script will prompt you for the password before mounting. It will then run the same as for physical media (except it cannot eject or close the tray).

Example:

Code:

$ whatson
mount /mnt/cdrom
