Find and delete files that contain same string in filename in linux terminal -

i want delete files folder contain not unique numerical string in filename using linux terminal. e.g.:

werrt-110009.jpg => delete asfff-110009.jpg => delete asffa-123489.jpg => maintain asffa-111122.jpg => maintain 

any suggestions?

i understand question, think. want remove files contain numeric value not unique (in particular folder). if filename contains value found in filename, want remove both files, right?

this how (it may not fastest way):

# put files in folder in list # array=(*) work make sure have enabled nullglob: shopt -s nullglob array=(*) delete=()  elem in "${array[@]}";     # each elem in list extract number     num_regex='([0-9]+)\.'     [[ "$elem" =~ $num_regex ]]     num="${bash_rematch[1]}"     # use extracted number check if unique     dup_regex="[^0-9]($num)\..+?(\1)"     # if not unique, put file in files-to-delete list     if [[ "${array[@]}" =~ $dup_regex ]];         delete+=("$elem")     fi done  # delete found duplicates elem in "${delete[@]}";     rm "$elem" done 

in example, array be:

array=(werrt-110009.jpg asfff-110009.jpg asffa-123489.jpg asffa-111122.jpg) 

and result in delete be:

delete=(werrt-110009.jpg asfff-110009.jpg) 

is meant?
