Tidy up a directory of ISO 8601 dated files

tidy-up-dated-files.sh

# Goes through directory of appropriately named files and decants into labeled year-month gzipped tarball archives
# Files MUST be dated in ISO format in filename, i.e. YYYY-MM-DD

# Currently set up to only work from 2010-2019; add extra loops for decades(/centuries etc) as needed

# First get rid of pesky spaces in names (which mess up the xargs command)
find -name "* *" -type f | rename 's/ /_/g'

# Then loop through desired files and sort into appropriate tarbals
for y in {1..9}
    do

    for mo in {01..12}
        do

        # Get the year
        m=$(printf "%02d" $mo)
        ym="201$y-$m"
        echo $ym

        # Tarball the desired files
        ls *$ym* | xargs tar -cvzf $ym.tar.gz

        # Remove the originals
        rm *$ym*
         
        # NB greater specificity could be added to the regex, e.g. '$ym*.jpg' would just sort jpg files
