I want to replace the string "Solve the problem" with "Choose the best answer" in only the xml files which exist in the subfolders of a folder. I have compiled a script which helps me to do this, but there are 2 problems

  1. It also replaces the content of the script
  2. It replaces the text in all files of the subfolders( but I want only xml to change)
  3. I want to display error messages(text output preferably) if the text mismatch happens in a particular subfolder and file.

So can you please help me modify my existing script so that I can solve the above 3 problems.

The script I have is :

find -type f | xargs sed -i "s/Solve the problem/Choose the best answer/g"

Using bash and sed:

search='Solve the problem' replace='Choose the best answer' for file in `find -name '*.xml'`; do grep "$search" $file &> /dev/null if [ $? -ne 0 ]; then echo "Search string not found in $file!" else sed -i "s/$search/$replace/" $file fi done

Not sure I understand issue 3.
