I have been clicking pictures in digital format since 2004 when I bought mobile phone with camera. It has been 13 years and I have lot of pictures. I used to manually organize the pictures by create a folder like YYYY-MM-DD_SOME_TEXT and for some reason I really like this format. These days people use Google Photos which is definitely amazing by I am still following the old fashioned way to manage the pics manually.
Most of the pictures I have taken in the past 13+ years are from mobile and stored in the memory card from from time to time I take them from mobile and store them separately by creating a folder by date. I feel lazy to create the folder by date manually and I used this nice shell script to create the folders with date name and nice organize all the pictures take on that date in that folder.
for x in *.jpg; do
d=$(date -r "$x" +%Y-%m-%d)
mkdir -p "$d"
mv -- "$x" "$d/"
If you are like me who likes to organize the pictures or in fact any file in this way, you can use the above shell script and even modify it to suit your requirements.
Have fun :)
