                Some of the useful bash commands which I use everyday
              
          
    Rename all files extension recursively eg. .js to .jsx

find . -name '*.js' -exec sh -c 'mv "$0" "${0%.js}.jsx"' {} \;
Convert all images in a specific format (eg .png or .jpg to webp)

for i in *; do convert $i "${i%.*}.webp"; done
