Sorry friends,

Even Im also trying for the same things,

Actually I have 4 report files each contains Jobs name, order date, run date and status. I have to generate one resultant report which looks to be:

job name Order date run date status

I've tried to select each column values into seperate variables and used echo.

echo "$var1\t" >> result.report
echo"$var2\t" >> result.report
echo "$var3\t" >> result.report
echo "$var4\n" >> result.report

It is working well but I want to know are there any ways to achieve this?

Your help will be appreciated.

Many Thanks and Regards.
Love

Hi,

Try this way...

Let us say, your data is in file1 file2 file3 and file4.

--------------------------------------------------------------------------
#!/bin/ksh

rm a1 b1 c1 d1

cat file1 | while read record
do
echo $record | cut -d" " -f1 >> a1
done

cat file2 | while read record
do
echo $record | cut -d" " -f1 >> b1
done

cat file3 | while read record
do
echo $record | cut -d" " -f1 >> c1
done

cat file4 | while read record
do
echo $record | cut -d" " -f1 >> d1
done

paste a1 b1 c1 d1
--------------------------------------------------------------------------
