mount — Mount/Attach a File System to a File Tree.
All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree.
$ mount — List all mounted FSs (FileSystem).
$ mount -l — List all mounted FSs with Labels.
# mount -a — Mount all entries in the /etc/fstab.
# mount /mnt/cdrom — Mount known device to cdrom dir. Mount will find the cdrom device (/dev/hdX) from /etc/fstab.
# mount /dev/hdd — Mount device at the known place. Mount will find the mount point (Ex. /mnt/cdrom) from /etc/fstab.
# mount -t ext2 /dev/hda2 /tmp/dir1 — Mount a Linux partition at /tmp/dir1.
# mount -t vfat -o rw,umask=0007 /dev/hda1 /mnt/C — Mount Windows FAT partition
# mount -o rw /dev/fd0 /mnt/floppy/ -t vfat — Mount FAT format floppy in Read and write mode.
# mount -t nfs 192.168.14.155:/home/one /home/one — Mount NFS partition, from a machine with particular IP, to /home/one dir.
# mount /tmp/fdimage /mnt/test1 -t msdos -o loop=/dev/loop3,blocksize=1024 — Mount msdos Floppy disk image via loopback device.
# mount /tmp/cdimg.iso /mnt/test1 -t iso9660 -o loop=/dev/loop3,blocksize=1024 — Mount a CD iso image via loopback device.
# mount –bind /mnt/cdrom /mnt/test1 — Mount the /mnt/cdrom in another location. So you can access in the FS in two places.
# mount -t tmpfs none /mnt/test1 -o rw,size=1m — Mount a tmpFS
# mount -t tmpfs none /mnt/test1 -o remount,ro,size=1m — Remount the same partition with different permission.
