The UFilAn Universal File Analyzer provides a simple to use file analyzing functionality. Main features:
- Read and write data from/to file or stdin
- Provides grpahical and text output
- Plots histogram and byte distributions
- Easy to use command line to combine ufilan with other unix tools
- ...
Usage: java -jar ufilan [-if <inputfile>] [-of <outputfile>] [-c <chunksize>]
[-s <seeksize>] -a <action> [<actionparam>]
-if <inputfile> path of the input file. If null the stdin is used
-of <outputfile> path of the output file. If null stdout is used
-c <chunksize> chunk size in bytes used for input parsing. Default value: 1 byte
-s <seeksize> skips the given number of bytes start parsing. Default value: 0 byte
-a histogram generate a text or graphic histogram. Param "text" or "img".
map generate a graphic distribution map
type analyze the input to determine the type
size calculate the input size
entropy calculate the entropy
Simple examples:
- Read data from stdin and print the type to stdout
java -jar ufilan -a type- Read data from stdin and save the graphic histogram to /tmp/histogram.bmp
java -jar ufilan -of /tmp/histogram.bmp -a histogram img- Read data from /tmp/in.xml and print the entropy information to stdout
java -jar ufilan -if /tmp/in.bmp -a entropyAdvanced examples:
- Read data from /tmp/input.txt with 2 byte chunks, skip the first 10 byte and print the most recent chunks
java -jar ufilan -if /tmp/input.txt -c 2 -s 10 -a histogram txt | head -n 11- Calculate the entropy of the unix random number generator
