How to: Extract files from ISO CD images in Linux

Under many situations you may need to get a single file/many files from Linux ISO image. You can mount ISO images via the loop device. You need to use mount command. First login as a root user: Extract File(s) Under Linux OS Let us assume that your ISO image name is disk1.iso. Step # 1: First you need to create a directory /mnt/iso # mkdir /mnt/iso # mount -o loop disk1.iso /mnt/iso Step # 3: Extract file Now you can easily copy file called file.txt from iso disk image to /tmp directory : # cd /mnt/iso # cp file.txt /tmp Step # 4: Copy foo.rpm from ISO disk image: # cd /mnt/iso/RedHat/RPMS # cp foo.rpm /tmp Extract File(s) Under Windows XP or Vista Os Windows do not have in built capability as provided by Linux to extract file. Luckly many third party software exist my favorite is Winimage Download trial version (I’m sure you will love to registered this tiny utility later): 1) Install Winimage software 2) Just double click on Linux ISO file 3) Select the desired file and hit CTRL + X (or from Image menu select extract) For more information read man pages: man cp man mv man rpm man mount man mkdir
