Free swap partition size software for linux

Partition Image application is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file.
The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example); partitions can be saved across the network since version 0.6.0.
Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file.
This is unlike the dd command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB.
This is very useful to save partitions to an image in some cases:
- First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you dont want the image to use hard-disk space.
- This utility can be used to install many identical PCs. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Images restore function.

Partition Logic is a free hard disk partitioning and data management tool. It can create, delete, format, and move partitions and modify their attributes. It can copy entire hard disks from one to another.

Partition Logic is free software, based on the Visopsys operating system. It boots from a CD or floppy disk and runs as a standalone system, independent of your regular operating system.

Partition Logic is intended to become a free alternative to such commercial programs as Partition Magic, Drive Image, and Norton Ghost...

Gpart is a tool which tries to guess the primary partition table of a PC-type hard disk in case the primary partition table in sector 0 is damaged, incorrect or deleted. The guessed table can be written to a file or device. Supported (guessable) filesystem or partition types by Gpart are:
- DOS/Windows FAT (FAT 12/16/32)
- Linux ext2
- Linux swap partitions versions 0 and 1 (Linux >= v2.2.X)
- OS/2 HPFS
- Windows NT/2000 FS
- *BSD disklabels
- Solaris/x86 disklabels
- Minix FS
- Reiser FS
- Linux LVM physical volume module (LVM by Heinz Mauelshagen)
- SGI XFS on Linux
- BeOS filesystem
- QNX 4.x filesystem
Enhancements:
- New support for the following filesystems: BeOS, QNX 4.x & SGI XFS.
- Updated Reiser filesystem support (Francis Devereux).
- Updated LVM support.
- Several small fixes from contributors.

Super Grub Disk is a bootable floppy or CDROM that is oriented towards system rescue, specifically for repairing the booting process.

Super Grub Disk is simply a Grub Disk with a lot of useful menus. It can activate partitions, boot partitions, boot MBRs, boot your former OS (Linux or another one) by loading menu.lst from your hard disk, automatically restore Grub on your MBR, swap hard disks in the BIOS, and boot from any available disk device.

The ISO has multi-language support, and allows you to change the keyboard layout of your shell.

This version has Gpareted included.

QTParted is a Partition Magic clone written in C++ using the Qt toolkit.
Some note about REISERFS/NTFS/JFS/EXT3 support in QTParted: Even if libparted does not support these filesystems QTParted can handle it. Of course it do it using external tools. This are the latest support status of this filesystems:
- Ntfs - Needed mkntfs and ntfsresize (linux-ntfs)
- ReiserFS - Needed (progsreiserfs) by libparted. Warning: progsreiserfs is not reisergsprogs!
- JFS - Needed mkfs.jfs (jfsutils)
- Ext2/Ext3 - Needed mkfs.ext3 (e2fsprogs)
- XFS - Needed mkfs.xfs (xfsprogs)

SYNOPSIS

Get the size for directory /etc/ with the block size of 1024 while following symbolic links:

my $obj = File::Size->new(
dir => /etc/,
blocksize => 1024,
followsymlinks => 1,
humanreadable => 1
);
print $obj->getsize(), "n";

File::Size is used to get the size of files and directories.

There are 6 methods you can use:

new

There are 4 optional hash values for the new() method:

dir

The directory you want the module to get the size for it. Default is current working directory.

blocksize

The blocksize for the output of getsize() method. default is 1 (output in bytes).

followsymlinks

If you want to follow symlinks for directories and files, use this option. The default is not to follow symlinks.

humanreadable

If you want output size in human readable format (e.g. 2048 -> 2.0K), set this option to 1.

You dont have to specify any of those options, which means this is okay:
print File::Size->new()->getsize(), " bytesn";

This is okay too:
print File::Size->new()->setdir( /etc/ )->setblocksize( 1024**2 )->getsize(), " MBn";

setdir

Used to set (or get - if called without parameters) the directory. Example: $obj->setdir( /etc/ );

setblocksize

Used to set (or get - if called without parameters) the block size. Example: $obj->setblocksize( 1024 );

setfollowsymlinks

Used to set if you want to follow symbolic links or not. If called without parmeters, returns the current state. Example: $obj->setfollowsymlinks( 1 );

sethumanreadable

Used to set (or get - if called without parameters) if you want human-readable output sizes. Example: $obj->sethumanreadable( 1 );

getsize

Used to calculate the total size of the directory. Prints output according to the block size you did or didnt specify.
