FSlint is a collection of utilities for identifying redundant data and other filesystem problems. It includes command-line tools and a graphical interface for examining directories and finding files that may require attention.
The software identifies several categories of filesystem clutter, including duplicate files, empty directories, broken symbolic links, temporary files and problematic filenames. Its separate command-line utilities allow individual checks to be performed without launching the graphical interface.
FSlint uses multiple stages when comparing duplicate files. It first examines file sizes and checksums to eliminate files that cannot match, reducing unnecessary full-content comparisons.
This is free and open source software.
Key Features
- Identifies duplicate files using file sizes and successive checksum comparisons.
- Distinguishes files sharing the same inode from separate copies.
- Finds empty directories and redundant temporary files.
- Detects broken symbolic links.
- Identifies filenames containing invalid characters or problematic encodings.
- Finds conflicting filenames and names that may cause problems on other filesystems.
- Reports files associated with invalid user or group identifiers.
- Identifies unstripped executable files.
- Finds redundant whitespace in supported text files.
- Provides separate command-line tools for individual filesystem checks.
- Supports recursive scanning of multiple directories.
- Allows matching files and other detected problems to be reviewed through a graphical interface.
- Provides tools for identifying potentially unused libraries and other redundant filesystem data.
- Supports translated interface messages.
