ExactFile

Usage: exf [OPTIONS] [HASH METHOD(s)] [FILE(s)]

  Options:
  -r         Recurse subdirectories
  -d PATH    Set working directory
  -otf FILE  Output to file instead of console (deletes file if exists)
  -c FILE    Use digest file to test files, report errors only
  -cv FILE   Use digest file to test files, verbose (report every file)
  -mt N      Set maximum hash threads to N

  -omd5      Output style: md5sum (default)
  -ofcmd5    Output style: FILECHECKMD5
  -osfv      Output style: Simple File Verification (defaults to -crc32 hash)
  -osha1     Output style: sha1sum (defaults to -sha1 hash)

  -fp        Output includes full paths.

  -md5sum    Same as <exf -r -otf exactfile.md5 -omd5 -md5 *.*>

  -license   Output exf EULA.

  Hash methods: (defaults to -md5, except for -osfv, -osha1)
  -adler32
  -crc32
  -md2
  -md4
  -md5
  -sha1
  -sha256
  -sha384
  -sha512
  -ripemd128
  -ripemd160
  -tiger128
  -tiger160
  -tiger192
  -gost

Notes:

  Maximum hash threads: exf defaults to 1 for written CD media. Otherwise, the
  number of processor cores is used, up to 16. exf will never use more than 16
  hash threads even if more is specified with -mt.

  When -c is specified, the working directory is set to the location of the
  digest file unless -d is specified.

  Using -otf will erase the output file specified if it already exists. Using
  this option ensures that the digest file being created will not be a part
  of the digest itself.

  -md5sum creates a digest file named "exactfile.md5" in the working directory,
  using the md5 hash method, with recursive subdirectory scanning of all files.
  Only -mt and -d are valid options when -md5sum is used.

  You can redirect console output to a file by appending > filename.txt to the
  command line. Note that if you redirect output to a file in the scanning
  path when creating a digest, and the file name matches the scanning file
  mask, an non-fatal error will be included in the digest file because exf
  will attempt to hash the output file while it is still being written.
  To avoid this, use the -otf FILE option.

Examples:

  exf -c sums.md5 -d C:\temp
    Tests files in digest file "sums.md5" (loads sums.md5 from current
    directory); assumes the files listed in the digest are in C:\temp.

  exf -c sums.md5
    Tests files in digest file "sums.md5"; assumes both the digest file and the
    files listed in the digest file are in the current directory.

  exf -c C:\temp\sums.md5
    Tests files in digest file "C:\temp\sums.md5"; assumes the files listed in
    the digest file are in the same folder as the digest file (C:\temp)

  exf -md5sum
    Creates a digest file in the current directory named "exactfile.md5" using
    the md5 hash method with recursive subdirectory scanning of all files of
    the current directory.

  exf -md5sum -d C:\temp
    Like above, but creates digest file "C:\temp\exactfile.md5" and scans files
    and subdirectories C:\temp

  exf -r -otf tempsums.md5 -d C:\temp *.txt *.exe
    Creates digest file "tempsums.md5" in C:\temp, scanning all of the files
    matching "*.txt" and "*.exe" in C:\temp and all subdirectories.

  exf -r -otf "C:\sums folder\tempsums.md5" -d C:\temp *.txt *.exe
    Same as above, but writes digest file to "C:\sums folder" instead.

  exf -crc32 -sha1 -md5 -gost myfile.zip
    Output CRC32, SHA1, MD5, and GOST hashes for myfile.zip in the current
    directory. Uses md5sum output format.
