I tried that but no luck...the file generaeted is blank. :-(

Code:

cat test.txt | \
sed -e "s/'[^']*'/NOTFOUND/g" >test.txt

I need to update the same file with the new string. pls help

use it like this..

Code:

sed -i "s/'[^']*'/NOTFOUND/g" infile

Code:

perl -i.bck -pe"
  s/'.*?'/NOTFOUND/g

Can I first find the text between string1= books.amazon=' and string2= ' (locate the text beween the cotes)

and then replace by NOTFOUND.!! this way i can replace multiple strings. I have tried this code but no luck..

Code:

sed -i 's/\(books.amazon='\)[^<]*\('\)/NOTFOUND/g' abc.txt

pls guide

Code:

cat books | sed 's/\(books.amazon=\)\(.*\)/\1NOTFOUND/'

books.amazon= is stored in \1
'Let me read' is stored in \2
