ie
VAR=`grep -n -e 'PATTERN' file`
How ever I am missing the line breaks in the variable , How do I store the resualts of grep with many lines in to a variables. I want the varable should be the sawmway as we do the grep

grep -n -e 'PATTERN' file`

shoeld be the same way as that of

var=`grep -n -e 'PATTERN' file`
echo $var

I need the $var for further processing

If you want to keep the value in a variable seperated by a new line you can do something like this:

Code:
OLDIFS=$IFS
IFS='\n'

var=`grep -n -e 'PATTERN' file`
echo $var

IFS=$OLDIFS
