Linux is a powerful open-source operating system that can run on a wide range of devices, from small embedded systems to large servers and even handhelds. As Linux has matured and become more stable, its open-source nature has made it increasingly popular around the world. Many enterprise environments now use a hybrid system combining UNIX, Linux, and Windows. This often requires data exchange between different platforms. In this article, I'll share practical methods for mounting CD image files, external hard drives, USB flash drives, Windows network shares, and UNIX NFS shares under Linux, based on my real-world experience.
The "mount" command in Linux allows you to attach a partition or device to a specific directory, effectively linking it to that location. When you access the directory, you're essentially accessing the contents of the mounted device.
**Understanding the Mount Concept:**
To access any file system other than the root, it must be "mounted" to a directory within the root file system. This process is called "mounting," and the target directory is referred to as the "mount point." Unmounting is the reverse process, where the association is broken.
1. **Mount**: This operation links an external file system to a directory in the root system, allowing access to its contents.
2. **Mount Point**: A designated directory used as an access point for another file system.
- It should already exist.
- It should not be used by other processes.
- Files present at the mount point will be hidden once the device is mounted.
**Using the Mount Command:**
The `mount` command is essential for attaching storage devices or network shares. The basic syntax is:
`mount [-t vfstype] [-o options] device dir`
- `-t vfstype`: Specifies the file system type. Usually, it's optional as `mount` detects it automatically.
- CD/CD image: `iso9660`
- DOS FAT16: `msdos`
- Windows FAT32: `vfat`
- Windows NTFS: `ntfs`
- Windows network share: `smbfs`
- UNIX/Linux network share: `nfs`
- `-o options`: Defines how the device is mounted.
- `loop`: Used to mount a file as a disk image.
- `ro`: Mount in read-only mode.
- `rw`: Mount in read-write mode.
- `iocharset`: Sets the character encoding for the file system.
- `device`: The actual device or file to be mounted.
- `dir`: The directory where the device will be mounted.
**Mounting a CD Image File:**
1. To create a CD image from a physical CD:
```bash
#cp /dev/cdrom /home/sunky/mydisk.iso
```
or
```bash
#dd if=/dev/cdrom of=/home/sunky/mydisk.iso
```
Both commands will create a `.iso` image of the CD in the specified location.
2. To create a CD image from a directory:
```bash
#mkisofs -r -J -V mydisk -o /home/sunky/mydisk.iso /home/sunky/mydir
```
This command generates a CD image from all files and folders in `/home/sunky/mydir`, with the volume label "mydisk".
3. To mount the CD image:
```bash
#mkdir /mnt/vcdrom
#mount -o loop -t iso9660 /home/sunky/mydisk.iso /mnt/vcdrom
```
After this, you can access the contents of the ISO file through `/mnt/vcdrom`.
By mastering these techniques, you can efficiently manage storage and network resources in a multi-platform environment, making Linux a versatile and reliable choice for both personal and enterprise use.
