Modifying replace string in xargs

Question

When I am using xargs sometimes I do not need to explicitly use the replacing string:

find . -name \"*.txt\" | xargs rm -rf

In oth

Answer 1

In cases like this, a while loop would be more readable:

find . -name "*.txt" | while IFS= read -r pathname; do
    base=$(basename "$pathname"); name=${base%.*}; ext=${base##*.}
    mv "$pathname" "foo/${name}.bar.${ext}"
done

Note that you may find files with the same name in different subdirectories. Are you OK with duplicates being over-written by mv?
