while using read command I want too.....
This is the greatest site ever, only my second day of use and the responses and advice I got from yesterdays question were great..
Now for todays question,
I have a file that I want to read one line at a time into a script i've written. Once I have read the line I would like to update it (in the same file) so that it has READ at the beginning of the line (so it can be easliy deleted later without removing unread lines).
Can this be easliy done in ksh on HPUX?
Any advice would be great.....

'Morning
vmstat 1 1|sed 1,2d|awk '{printf("%s\n",$1)}'|read var
echo $var
This syntax run on AIX (ksh) but not on linux (bash).
I think that problem is the read command, because the following syntax is ok :
vmstat 1 1|sed 1,2d|awk '{printf("%s\n",$1)}'
Could someone help me!

Trying to use the read command. How do you add a 2nd option? In this example I'd like to offer two options, pre and post. If you answer pre, you get one output but if you answer post, you get another output.
echo Is this pre or post?
read pre

then echo You have typed pre.

CHING(6) Games Manual CHING(6) NAME
ching, fortune - the book of changes and other cookies SYNOPSIS
/usr/games/ching [ hexagram ] /usr/games/fortune DESCRIPTION
The I Ching or Book of Changes is an ancient Chinese oracle that has been in use for centuries as a source of wisdom and advice. The text of the oracle (as it is sometimes known) consists of sixty-four hexagrams, each symbolized by a particular arrangement of six straight (---) and broken (- -) lines. These lines have values ranging from six through nine, with the even values indicating the broken lines. Each hexagram consists of two major sections. The Judgement relates specifically to the matter at hand (E.g., "It furthers one to have somewhere to go.") while the Image describes the general attributes of the hexagram and how they apply to one's own life ("Thus the supe- rior man makes himself strong and untiring."). When any of the lines have the values six or nine, they are moving lines; for each there is an appended judgement which becomes signifi- cant. Furthermore, the moving lines are inherently unstable and change into their opposites; a second hexagram (and thus an additional judgement) is formed. Normally, one consults the oracle by fixing the desired question firmly in mind and then casting a set of changes (lines) using yarrow-stalks or tossed coins. The resulting hexagram will be the answer to the question. Using an algorithm suggested by S. C. Johnson, the Unix oracle simply reads a question from the standard input (up to an EOF) and hashes the individual characters in combination with the time of day, process id and any other magic numbers which happen to be lying around the system. The resulting value is used as the seed of a random number generator which drives a simulated coin-toss divination. The answer is then piped through nroff for formatting and will appear on the standard output. For those who wish to remain steadfast in the old traditions, the oracle will also accept the results of a personal divination using, for example, coins. To do this, cast the change and then type the resulting line values as an argument. The impatient modern may prefer to settle for Chinese cookies; try fortune. SEE ALSO
