I have a problem in the following code ...
Code:
while read line
do
#Get Line Number
OLDLINE=`sed -n $Lineno $filename`
echo "Un Changed Line : "$OLDLINE
echo "Enter a New Pattern : "
read NewPattern <&1
echo "NewPattern :"$NewPattern
NEWLINE=`cat $filename | sed -n $Lineno | sed s/$OldPattern/$NewPattern/`
echo $NEWLINE
LINECHANGE=`sed s/$OLDLINE/$NEWLINE/ $filename`
echo $LINECHANGE
ChangedLine=`sed -n $Lineno $filename`
echo "Changed Line : "$ChangedLine
done < $INT_FILE
I am trying to read a line from a file and get the line and change a pattern in the line and i want to replace the
OLD line with the NEW line.
I have problem in the following line
Code:
LINECHANGE=`sed s/$OLDLINE/$NEWLINE/ $filename`
the OLD Line is not changed in NEW Line in the file.
is there any problem with the command i gave or should i need to correct it
Can anyone please help.
Thanks
Rahul
