Hi,
Is it possible to delcare hashes in KSH the way we do it in Perl.

fruits="healthy"
fruits="sour"
echo fruits
Ofcourse this piece of code does not work in KSH. Please let me know if there is a way of doing it in KSH.

Let's assume that I have a file with contents delimited by pipe:

How would I use 'substr' to get the 3rd field. For example, "the" from the first line, and "little" from the second line?

Hi Everyone,
$tmp="20090620231013";
$tmp = substr($tmp,0,8)." ".substr($tmp,8,2).":".substr($tmp,10,2).":".substr($tmp,12,2);
So my output is:
20090620 23:10:13.
I only can think substr is easy, any perl can do this just one line very simple efficient one? :eek:

cfdisk
CFDISK(8) GNU cfdisk Manual CFDISK(8)
NAME
GNU cfdisk - a curses-based partition table manipulation program
SYNOPSIS
cfdisk [options] [device]
DESCRIPTION
cfdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive
using a simple menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space
for new operating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types
option below.
OPTIONS
-h, --help
displays a help message.
-v, --version
displays the program's version.
-a, --arrow-cursor
use an arrow cursor, instead of reverse video highlighting, in case your terminal doesn't support it.
-z, --new-table
create a new partition table on the disk. This is useful if you want to change the partition table type or want to repartition you
entire drive. Note that this does not delete the old table on the disk until you commit the changes.
-u, --units=UNIT
sets the default display units to UNIT. A list of possible units is given below.
-t, --list-partition-types
displays a list of supported partition types and features.
UNITS
You can choose in what unit cfdisk should display quantities like partition sizes. You can choose from sectors, percents, bytes, kilobytes,
etc. Note that one kilobyte is equal to 1,000 bytes, as this is consistent with the SI prefixes and is used by hard disk manufacturers. If
you prefer to see the sizes in units with binary prefixes, you should instead select one kilo binary byte (kibibyte), which is equal to
1,024 bytes. Whatever display unit you have chosen, you can always enter the quantities in the unit of your choice, for example 1000000B or
1000kB.
compact
display each size in the most suitable unit from B, kB, MB, GB and TB.
B one byte
kB one kilobyte (1,000 bytes)
MB one megabyte (1,000,000 bytes)
GB one gigabyte (1,000,000,000 bytes)
TB one terabyte (1,000,000,000,000 bytes)
KiB one kilo binary byte (1,024 bytes)
MiB one mega binary byte (1,048,576 bytes)
GiB one giga binary byte (1,073,741,824 bytes)
TiB one tera binary byte (1,099,511,627,776 bytes)
s one sector. It depends on the sector size of the disk. You can use it if you want to see or choose the exact size in sectors.
% one percent from the size of the disk
cyl one cylinder. It depends on the cylinder size.
chs use CHS display units.
BUGS
There are no known bugs. We are in early stages for development, so be careful.
