DownloadThis program intentionally corrupts a unix stream at a specified error rate. It is for systematic analysis on the effects of data corruption. I wrote it to simulate bit-rot in file archives so I could test RAID and archive strategies for data recovery. A few short bash scripts are included so you can instantly enjoy text, image, audio, and video corruption. Just drop in your own data files called test.jpg, test.mp3, and test.mp4 and run the scripts.
Usage format is:
corrupt [OPTION]... [FILE]
where:
OPTIONS
-bit single bit error instead of byte substitution corruption
-B NUM_B number of bytes per a single corruption event
-kB NUM_KB number of kilobytes per a single corruption event
-MB NUM_MB number of megabytes per a single corruption event
-u uniform corruption instead of a random statistical event
-c CHAR substitute a constant CHAR instead of a random bit/byte error
Features
- bit or byte level corruption
- user defined error rate specified in B, kB, or MB
- statistical or uniform error distribution
