Recursively remove files those size is less than 1MB

Question

How do I recursively remove files that are less than 1MB in size from a directory?

Answer 1

This can be done with find:

find . -type f -size -1M -exec rm {} +

Note that this will recursively descend into subdirectories, and will unconditionally delete all files smaller than 1 megabyte. Be careful.

Answer 2

This should do the job:

$ find <directory> -type f -size -1M -delete

Answer 3

Just for variety and a possible (probably marginal) performance gain:

find <directory> -type f -size -1M -print0  | xargs -0 rm

Answer 4

Try

find . -size -1M -exec rm {} \;

Answer 5

You can checkout this link http://ayaz.wordpress.com/2008/02/05/bash-quickly-deleting-empty-files-in-a-directory/ , it has exactly what you want.

for file in *;
  do
    file_size=$(du $file | awk '{print $1}');
    if [ $file_size == 0 ]; then
        echo "Deleting empty file $file with file size $file_size!";
        echo "rm -f $file";
    fi;
done

You can iterate through all the files with a for loop and then use du and awk to find the filesize like in the above example.
