Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)

Hi,
I was trying to dos2unix a file that has some special characters but dos2unix converted those into different format. I am working on sun server.
I guess the default for dos2unix on sun server is ISO format .
Can i change the format so that it does the conversion in UTF format?

MKSWAP(8) Linux Programmer's Manual MKSWAP(8)NAME
mkswap - set up a Linux swap area
SYNOPSIS
mkswap [-c] [-f] [-p PSZ] [-L label] [-U uuid] device [size]
DESCRIPTION
mkswap sets up a Linux swap area on a device or in a file.
The device argument will usually be a disk partition (something like /dev/sdb7) but can also be a file. The Linux kernel does not look at
partition IDs, but many installation scripts will assume that partitions of hex type 82 (LINUX_SWAP) are meant to be swap partitions.
(Warning: Solaris also uses this type. Be careful not to kill your Solaris partitions.)
The size parameter is superfluous but retained for backwards compatibility. (It specifies the desired size of the swap area in 1024-byte
blocks. mkswap will use the entire partition or file if it is omitted. Specifying it is unwise -- a typo may destroy your disk.)
The PSZ parameter specifies the page size to use. It is almost always unnecessary (even unwise) to specify it, but certain old libc ver-
sions lie about the page size, so it is possible that mkswap gets it wrong. The symptom is that a subsequent swapon fails because no swap
signature is found. Typical values for PSZ are 4096 or 8192.
After creating the swap area, you need the swapon command to start using it. Usually swap areas are listed in /etc/fstab so that they can
be taken into use at boot time by a swapon -a command in some boot script.
WARNING
The swap header does not touch the first block. A boot loader or disk label can be there, but it is not a recommended setup. The recom-
mended setup is to use a separate partition for a Linux swap area.
mkswap, like many others mkfs-like utils, erases the first block to remove old on-disk filesystems.
mkswap refuses to erase the first block on a device with a disk label (SUN, BSD, ...) or on a whole disk (e.g. /dev/sda).
OPTIONS -c Check the device (if it is a block device) for bad blocks before creating the swap area. If any are found, the count is printed.
-f Force -- go ahead even if the command is stupid. This allows the creation of a swap area larger than the file or partition it
resides on.
Without this option, mkswap will refuse to erase the first block on a device with a partition table or on a whole disk (e.g.
/dev/sda).
-L label
Specify a label, to allow swapon by label.
-p PSZ Specify the page size (in bytes) to use. This option is usually unnecessary, mkswap reads the size from the kernel.
-U uuid
Specify the uuid to use. The default is to generate a UUID.
-v1 Specify the swap-space version. The old -v0 option has become obsolete and now only -v1 is supported.
The kernel has not supported v0 swap-space format since 2.5.22. The new version v1 is supported since 2.1.117.
NOTES
The maximum useful size of a swap area depends on the architecture and the kernel version. It is roughly 2GiB on i386, PPC, m68k and ARM,
1GiB on sparc, 512MiB on mips, 128GiB on alpha, and 3TiB on sparc64. For kernels after 2.3.3 there is no such limitation.
Note that before version 2.1.117 the kernel allocated one byte for each page, while it now allocates two bytes, so that taking into use a
swap area of 2 GiB might require 2 MiB of kernel memory.
Presently, Linux allows 32 swap areas (this was 8 before Linux 2.4.10). The areas in use can be seen in the file /proc/swaps (since
2.1.25).
mkswap refuses areas smaller than 10 pages.
If you don't know the page size that your machine uses, you may be able to look it up with "cat /proc/cpuinfo" (or you may not -- the con-
tents of this file depend on architecture and kernel version).
To set up a swap file, it is necessary to create that file before initializing it with mkswap, e.g. using a command like
# dd if=/dev/zero of=swapfile bs=1024 count=65536
Note that a swap file must not contain any holes (so, using cp(1) to create the file is not acceptable).
