How to make a FOR loop to move files to directory based on file extension - linux

Question

Im trying to sort thousands of files and put them in their own folder based on file extension. For example, JPG files to go into a JPG folder.
How can I create a for loop to address this?
What I have attempted to far:
# This listed out all the file extensions and the count for each extension:
find . -type f | rev | cut -d. -f1 | rev | tr '[:upper:]' '[:lower:]' | sort | uniq --count | sort -rn
#This was able to find all jpegs in the media folder
find /media -iname '*.jpg'
# This worked, however the MV command does not create the folder
find /media -iname '*.jpg' -exec mv '{}' /media/genesis/Passport/consolidated/jpg/ \; #
Im guessing that the for loop would be something like but I cant seem to figure it out:
for dir in 'find /media -iname "*.jpg"'; do
mkdir $dir;
mv $dir/*;
done

To find all the files of a particular extension and move then to a destination we can use find command as follows:
find . -name "*.jpg" -exec mv {} $destination/ \;
This being the critical logic, you can just create a for loop on top of this to iterate through all the known file extensions in your media folder
## List all the known extensions in your media folder.
declare -a arr=("jpg" "png" "svg")
## Refer question 1842254 to get all the extentsions in your folder.
## find . -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u
## now loop through the above array
for i in "${arr[#]}"
do
echo "$i"
## Create a directory based on file extension
destination="$i"
mkdir $destination
find /media -iname "*.$i" -exec mv {} $destination/ \;
done
Note that you can change your destination to be whatever you want. I just left it in the same directory.
