linux批量修改文件后缀

linux下生成的文件不加后缀的话会自己生成后缀lst
下面是批量修改文件后缀变为不带后缀

find /filePath -type f -name '*.lst' -print |
while read filename
do
    mv --backup=numbered "$filename" "$(dirname "$filename")/$(basename "$filename" '.lst')"
done

修改为txt后缀

find /filePath -type f -name '*.lst' -print |
while read filename
do
    mv --backup=numbered "$filename" "$(dirname "$filename")/$(basename "$filename" '.lst').txt"
done
