ber_dupbv - Linux
Overview
ber_dupbv
identifies duplicate files based on their content, even if the file names or sizes differ. This proves particularly useful in scenarios like cleaning up large file collections, detecting plagiarism, or finding identical files across multiple systems.
Syntax
ber_dupbv [options] <dirs>
Options/Flags
-a
,--all
: Include hidden files and directories in the search.-d
,--depth
: Set the maximum depth of subdirectories to search. Defaults to 1, meaning only the specified directories will be scanned.-p
,--print
: Display a list of all duplicate files found.-r
,--recurse
: Recursively descend into all subdirectories, regardless of-d
.-s
,--silent
: Only display a count of duplicate files found, without their paths.-v

Examples
Find duplicate files in the current directory:
ber_dupbv .
Recursively find duplicate files in all subdirectories:
ber_dupbv -r .
Print a list of duplicate files:
ber_dupbv -p .
Only display a count of duplicate files:
ber_dupbv -s .
Common Issues
- Duplicate files with different names:
ber_dupbv
relies on content comparison, so files with different names but identical content will be identified as duplicates. - Sparse files:
ber_dupbv
may not correctly identify duplicate sparse files. - Permissions errors: If
ber_dupbv
lacks sufficient permissions to access a file, it will skip that file.
Integration
- Combine with
find
to search for specific file types:
find . -type f -exec ber_dupbv -p {} +
- Use
xargs
to operate on the list of duplicate files:
ber_dupbv -p . | xargs rm -i
