Find All Zero-Byte Files in Directory and Subdirectories

Find all zero-byte files in directory and subdirectories

To print the names of all files in and below $dir of size 0:

find "$dir" -size 0

Note that not all implementations of find will produce output by default, so you may need to do:

find "$dir" -size 0 -print

Two comments on the final loop in the question:

Rather than iterating over every other word in a string and seeing if the alternate values are zero, you can partially eliminate the issue you're having with whitespace by iterating over lines. eg:

printf '1 f1\n0 f 2\n10 f3\n' | while read size path; do
    test "$size" -eq 0 && echo "$path"; done

Note that this will fail in your case if any of the paths output by ls contain newlines, and this reinforces 2 points: don't parse ls, and have a sane naming policy that doesn't allow whitespace in paths.

Secondly, to output the data from the loop, there is no need to store the output in a variable just to echo it. If you simply let the loop write its output to stdout, you accomplish the same thing but avoid storing it.

How to delete many 0 byte files in linux?

Use find combined with xargs.

find . -name 'file*' -size 0 -print0 | xargs -0 rm

You avoid to start rm for every file.

Using bash I need to perform a find of 0 byte files but report on their existence before deletion

With prompting from @JonathanLeffler I have succeeded with the following:

#!/bin/bash
## call this script with: find . -type f -empty -exec handleEmpty.sh {} +
for file in "$@"
do
  file2="$(basename "$file")"
  echo "$file2" >> "$(dirname "$file")"/deletedFiles.txt
  rm "$file"
done

This means I retain a trace of the removed files in a deletedFiles.txt flag file in each respective directory for the users to see when files are missing. That way, they can pursue going back to archive CD's to retrieve these deleted files, which are hopefully not 0 byte files.

Thanks to @John1024 for the suggestion of using the empty flag rather than size.

How to find zero byte files in Amazon S3

There is no direct process to search files of zero bytes in size at amazon s3. You can do it by listing all objects and then sort that items on the basis of size, then you can get all zero file size together.

if you want get list of all file having size zero then you can use Bucket Explorer and list the objects of the selected bucket then click on size header (sort by size) it will keep together files size of zero byte together.

Disclosure: I am a developer of Bucket Explorer.

remove all the files of zero size in specified directory

find . -size 0c -delete removes all such files in the current folder.

find and delete zero Byte file in HDFS

Try using this:

for f in $(hdfs dfs -ls -R / | awk '$1 !~ /^d/ && $5 == "0" { print $8 }'); do hdfs dfs -rm "$f"; done
