Example

F:\>ch file1.txt
file_sha256("file1.txt") = ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad

F:\>ch file1.txt file2.txt
file_sha256("file1.txt") = ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
file_sha256("file2.txt") = 9834876dcfb05cb167a5c24953eba58c4ac89b1adf57f28f2f9d09af107ee8f0
[NOT EQUAL]

[EQUAL]

F:\>ch -f md5 file1.txt
file_md5("file1.txt") = 900150983cd24fb0d6963f7d28e17f72

F:\>ch file1.txt 900150983cd24fb0d6963f7d28e17f72

List of Options

 [none] / -c         Get file hash and compare it to hash or hash of other file
  (--compare)        Comparing is optional. If you don't want to compare, enter only the one filename.
                     If you want to compare, enter a filename or hash.
                     Based on the used characters and the length of the second input,
                     it automatically determines whether it is a file or a hash and what type of hash.
                     If you want to be sure about the interpretation of the input, use -cf or -ch.
                     You can also use -f to select the hash function.
                     Examples:
                      ch file1.txt
                      ch file1.txt file2.txt
                      ch file1.txt ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
 -g                  Get the hash for each file from input.
  (--get-hash)       Calculates a hash for each input file.
                     Examples:
                      ch -g file1.txt file2.txt file3.txt
 -s [strings]        Hash of string.
  (--string-hash)    Calculates the hash for string or strings.
                     Examples:
                      ch -s "Example string"
                      ch -s "First string" "Second string"
 -cf                 Get file hash and compare it to hash of other file
  (--compare-files)  Similar to -c, but takes the second argument always as a filename.
                     Examples:
                      ch -cf file1.txt file2.txt
 -ch                 Get file hash and compare it to hash on input
  (--compare-hashes) Similar to -c, but takes the second argument always as a hash.
                     Unlike -c it does not automatically detect the type of hash function when neither is set.
                     It uses SHA-256 by default.
                     Examples:
                      ch -ch file1.txt ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
 -f [function]       Sets the selected hash function.
  (--hash-function)  Default hash function is SHA-256.
                     To get list of all available hash functions,
                     use the -f option without any additional arguments.
                     Examples:
                      ch -f
                      ch -f md5 file1.txt
                      ch -f sha512 -g file1.txt file2.txt
 -so                 Simple output.
  (--simple-output)  Simplifies the output.
                     When comparing, it gives 1 at the end when equal or 0 when different.
                     Examples:
                      ch -so file1.txt file2.txt
                      ch -h -so file1.txt file2.txt file3.txt
 -i (--information)  Information about checkHash.
 -fi(--full-info)    Full info about checkHash.
 -v (--version)      Information about checkHash version.
 -h / -? (--help)    Display this help message.
