Shell Programming and Scripting

Hi,
This is what happened after I came back from vacation: I don't remember how to do some simple things anymore.

I have a variable being passed in Kshell script. I only know the variable is like string: "str1 str2 str3 ....", and they are separated with blank spaces. I need to separate each field to do some data processing. Does anyone have some ideas?


THANKS for the help!

Try this ...

#!/usr/bin/ksh

while test $# -ne 0
do
echo $1
shift
done

That's pretty good thought if my variable is passed through command line.
But unfortunately my variable is not passed by the command line.
It's the variable passed by read command.

# GET INTERVIEWER LIST
/usr/ucb/echo "Enter interviewer numbers seperated by blank or leave blank for a
ll interviewers"
/usr/ucb/echo -n "ENTER: "

read intvw

?

Code:

for foo in $intvw
do
    echo $foo
    # do something with $foo
done

EDIT:

For info - you could use a method similar to bhargav

Code:

#!/bin/sh

echo "Enter space-seperated stuff..."
read intvw

set -- $intvw

while [ "$#" -ne "0" ]
do
   echo "$1"
   shift
done

Cheers

one more alternative :



echo "enter input: "
read abc

for i in `echo $abc`
do
echo $i
done
