Function:De-Duplication,File Management


FSlint is a utility to find and clean various forms of unwanted extraneous files on a computer file system. This excess of unnecessary files is referred to as lint. FSlint will help find unwanted or problematic lint in your files or file names. The most common forms of lint FSlint finds are duplicate files, empty directories, and improper names. FSlint has multiple tools to perform a multitude of tasks in both the graphical interface and command line modes.

There are a total of ten utilities available in both FSlint's graphical and command-line modes, plus two others (find and zipdir) that are available in command-line mode only:

  • findup - find DUPlicate files
  • findnl - find Name Lint (problems with filenames)
  • findu8 - find filenames with invalid utf8 encoding
  • findbl - find Bad Links (various problems with symlinks)
  • findsn - find Same Name (problems with clashing names)
  • finded - find Empty Directories
  • findid - find files with dead user IDs
  • findns - find Non Stripped executables
  • findrs - find Redundant Whitespace in files
  • findtf - find Temporary Files
  • findul - find possibly Unused Libraries
  • zipdir - Reclaim wasted space in ext2 directory entries
