E2TOOLS(7) Miscellaneous Information Manual E2TOOLS(7) NAME
e2tools - utilities to manipulate files in an ext2/ext3 filesystem DESCRIPTION
E2tools is a simple set of GPL'ed utilities to read, write, and manipulate files in an ext2/ext3 filesystem. These utilities access a filesystem directly using the ext2fs library. I wrote these tools in order to copy files into a linux filesystem on a machine that does not have ext2 support. Of course, they can also be used on a linux machine to read/write to disk images or floppies without having to mount them or have root access. Supported functionality: e2cp copy files e2mv move files e2rm remove files e2mkdir create directory e2ln create hard links e2ls list files/directories e2tail output the last part of a file In general, to specify a directory or file on an ext2 filesystem for the e2tools utilities, use the following form: filesystem:directory_path The filesystem can be an unmounted partition or a regular file that's been formatted to contain an ext2 filesystem. In general, if a com- mand takes multiple file names on the command line, if the first one contains an ext2 file specification, the rest of the files are assumed to be on the same filesystem until another one is explicitly stated: /tmp/boot.img:/tmp/file1 /tmp/file2 /tmp/file3 /tmp/boot2.img:/tmp/file4 Files 1-3 are on /tmp/boot.img and the last file is on /tmp/boot2.img SEE ALSO

RESIZE2FS(8) System Manager's Manual RESIZE2FS(8) NAME
resize2fs - ext2/ext3/ext4 file system resizer SYNOPSIS
resize2fs [ -fFpPM ] [ -d debug-flags ] [ -S RAID-stride ] device [ size ] DESCRIPTION
The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line resizing. (As of this writing, the Linux 2.6 kernel supports on-line resize for filesystems mounted using ext3 only.). The size parameter specifies the requested new size of the filesystem. If no units are specified, the units of the size parameter shall be the filesystem blocksize of the filesystem. Optionally, the size parameter may be suffixed by one of the following the units designators: 's', 'K', 'M', or 'G', for 512 byte sectors, kilobytes, megabytes, or gigabytes, respectively. The size of the filesystem may never be larger than the size of the partition. If size parameter is not specified, it will default to the size of the partition. The resize2fs program does not manipulate the size of partitions. If you wish to enlarge a filesystem, you must make sure you can expand the size of the underlying partition first. This can be done using fdisk(8) by deleting the partition and recreating it with a larger size or using lvextend(8), if you're using the logical volume manager lvm(8). When recreating the partition, make sure you create it with the same starting disk cylinder as before! Otherwise, the resize operation will certainly not work, and you may lose your entire filesystem. After running fdisk(8), run resize2fs to resize the ext2 filesystem to use all of the space in the newly enlarged partition. If you wish to shrink an ext2 partition, first use resize2fs to shrink the size of filesystem. Then you may use fdisk(8) to shrink the size of the partition. When shrinking the size of the partition, make sure you do not make it smaller than the new size of the ext2 filesystem! OPTIONS
-d debug-flags Turns on various resize2fs debugging features, if they have been compiled into the binary. debug-flags should be computed by adding the numbers of the desired features from the following list: 2 - Debug block relocations 4 - Debug inode relocations 8 - Debug moving the inode table -f Forces resize2fs to proceed with the filesystem resize operation, overriding some safety checks which resize2fs normally enforces. -F Flush the filesystem device's buffer caches before beginning. Only really useful for doing resize2fs time trials. -M Shrink the filesystem to the minimum size. -p Prints out a percentage completion bars for each resize2fs operation, so that the user can keep track of what the program is doing. -P Print the minimum size of the filesystem and exit. -S RAID-stride The resize2fs program will heuristically determine the RAID stride that was specified when the filesystem was created. This option allows the user to explicitly specify a RAID stride setting to be used by resize2fs instead. KNOWN BUGS
The minimum size of the filesystem as estimated by resize2fs may be incorrect, especially for filesystems with 1k and 2k blocksizes. AUTHOR
