Hi Reddy,
The below script will work for you, mainStr="abacus" old_word="ab" new_word="cd" result=`cat $mainStr | sed "s/$old_word/$new_word/g"` Last edited by apsprabhu; 03-17-2008 at 08:58 AM.. Reason: Missed out |

Hi
This is the same question you posted in: Need help regarding replacing a part of string Please folow the forum rules and do not multiple post.... however...following examples should help you on your way a little: Code:
# mainstr="abacus sabre" # echo $mainstr abacus sabre # echo $mainstr | sed 's/ab/cd/g' cdacus scdre # echo $mainstr abacus sabre # mainstr=`echo $mainstr | sed 's/ab/cd/g'` # echo $mainstr cdacus scdre |
