My phone saves pictures with names in the format<\/p>\n

IMG_YYYYMMDD_HHMMSS.jpg<\/pre>\n
I upload all images to my machine in a single directory, but I want to sort them by date. I use the following commands to sort them, in two phases :<\/p>\n
First, create the directories<\/strong><\/p>\n
ls|cut -d_ -f2|sort -u|while read date; do\nmkdir -p \/data\/pictures\/${date:0:4}\/${date:0:4}-${date:4:2}-${date:6:2};\ndone<\/pre>\n
    \n
  • ls<\/code> gives all image names<\/li>\n
  • cut -d_ -f2<\/code> extracts the date of each picture<\/li>\n
  • sort -u<\/code> removes duplicate dates with the -u (unique) option<\/li>\n
  • while read date<\/code> loops on all dates to run the next command<\/li>\n
  • mkdir -p<\/code> creates the directory for the date, and eventually the year<\/li>\n
  • The syntax ${date:0:4}<\/code> extract parts of the date. In this case the year<\/li>\n<\/ul>\n
    Then move images into directories<\/strong><\/p>\n
    ls|cut -d_ -f2|sort -u|while read date; do\nmv *$date* \/data\/pictures\/${date:0:4}\/${date:0:4}-${date:4:2}-${date:6:2};\ndone<\/pre>\n
    Only the command inside the loop is different :<\/p>\n
      \n
    • mv *$date*<\/code> moves all pictures of the same day in the target directory<\/li>\n<\/ul>\n
      If the date is not in the file name, but is available in the directory, you can get it with the command ls --full-time<\/code> and parse the output, or you can use the command stat<\/code> to get exactly what you want, as it gives you full control on the output.<\/p>\n","protected":false},"excerpt":{"rendered":"
