TurboSFV - Com­mand-line versions Overview Along with the GUI version, TurboSFV comes with com­mand-line versions for the creation of check­sum files and the validation of checksums. The command-line versions provide a similar functio­nality like the GUI version and can properly handle file and path names, which contain Unicode characters. They are implemented as a x86 version for 32-bit Windows and a x64 version for 64-bit Windows. The command-line versions actually support the follow­ing hash types: CRC-32, MD5, SHA-1, XXH32, XXH64, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256, BLAKE2S-256, BLAKE2SP-256, BLAKE2B-256, BLAKE2B-384, BLAKE2B-512, BLAKE2BP-256, BLAKE2BP-384, BLAKE2BP-512, BLAKE3-256, BLAKE3-512, BLAKE3-1024, BLAKE3-2048, SHA3-224, SHA3-256, SHA3-384 and SHA3-512. The following file extensions for hash files are used: bk3 BLAKE3-256, BLAKE3-512, BLAKE3-1024, BLAKE3-2048 blk BLAKE2S-256, BLAKE2SP-256, BLAKE2B-256, BLAKE2B-384, BLAKE2B-512, BLAKE2BP-256, BLAKE2BP-384, BLAKE2BP-512 md5 MD5 sfv CRC-32 sh1 SHA-1 sh2 SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256 sh3 SHA3-224, SHA3-256, SHA3-384, SHA3-512 xxh XXH32, XXH64 The command-line versions can be star­ted from within a console window or can be used in batch files, where an exit code returns a status information about the last operation. The output can be redirected to a file. Command-line: Create TurboSFV LE: PE: CE: XE: This version can be used to calculate hash values for files and to save them in a hash file for a later vali­dation. Check­sums can be generated for all files in a folder or for specific files: By using a file mask or filters, the number of files can be limited. During the calcu­lation of the checksums, the following text-based progress infor­mation is displayed: Progress in percent Actual number of files versus total number of files Time Current speed Current file name With a set of command-line swit­ches, the program behavior can be controlled: Switch Meaning /a Specifies the hash algorithm. /b Shows a modal message box depending on the exit code. /c Specifies the number of CPUs to be used for parallel working algo­rithms from the BLAKE family. /d Instead of the normal x86/x64 CPU instruc­tions, for SHA-1 the SSE based instruc­tions SHA1RNDS4, SHA1MSG1, SHA1MSG2, SHA1NEXTE and for SHA-256 and SHA-224, the SSE based instruc­tions SHA256RNDS2, SHA256MSG1, SHA256MSG2 will be used for the calcu­lation of checksums. For algo­rithms from the BLAKE3 family (BLAKE3-256, BLAKE3-512, BLAKE3-1024, BLAKE3-2048), a special SSE based imple­men­tation will be used, if TurboSFV is running on a 64 bit opera­ting system. The CPU must support the needed instruc­tions. /e Specifies the encoding for the hash file (ANSI, UTF-8, UTF-16 or Auto). /f Adds full path information for each file to the hash file. /g Specifies name and location of the log file. /h Hides progress updates in the console window. /i Includes files in sub folders. /j Checksums will be saved in capital letters. /k Create a backup of an existing check­sum file. /l Line feed type in the hash file (Windows or Unix). /n Specifies name and location of the hash file. /o Allows to overwrite an existing hash file. /p Reads data physically from fixed drives. /q For some algorithms, an identifier for the hash type will be saved as a commentary line and not together with the hash value (not compa­tible with previous versions: v10.10 and older). /r Reverse sort order of file names in the hash file. /s Display of de­tailed error messages. /t Adds a time­stamp to the hash file name. /u For files located on a network drive, the UNC path will be saved in the hash file instead of the drive letter. /v Filter for file attributes to limit the number of files. /w Filter for file names and extensions to limit the number of files. /x No commen­tary lines with addi­tional information. /y Scan mode in folder tree. /z Adds the file size of each file to the hash file (only for SHA family). /?

This checksum file contains check­sums, which you have previously calcu­lated either by the GUI version or by the command-line version. A text-based status line informs about the progress during the vali­dation: Progress in percent Files checked versus total number of files Number of files, for which the vali­dation passed. Number of files, for which the vali­dation failed. Time Current speed Current file name Similar to the other command-line version, a set of command-line switches is avaliable: Switch Meaning /a Analysis the hash file instead of starting the validation. Optionally, the analysis includes an availability check (counts how many files actually exist) and a search for new files, which detects files not listed in the hash file. /b Shows a modal message box depending on the exit code. /c Specifies the number of CPUs to be used for parallel working algo­rithms from the BLAKE family. /d Instead of the normal x86/x64 CPU instruc­tions, for SHA-1 the SSE based instruc­tions SHA1RNDS4, SHA1MSG1, SHA1MSG2, SHA1NEXTE and for SHA-256 and SHA-224, the SSE based instruc­tions SHA256RNDS2, SHA256MSG1, SHA256MSG2 will be used for the calcu­lation of checksums. For algo­rithms from the BLAKE3 family (BLAKE3-256, BLAKE3-512, BLAKE3-1024, BLAKE3-2048), a special SSE based imple­men­tation will be used, if TurboSFV is running on a 64 bit opera­ting system. The CPU must support the needed instruc­tions. /f Specifies the search path for new files. /g Specifies name and location of the log file. /h Hides progress updates in the console window. /i Includes sub folders, while searching for new files. /p Reads data physically from fixed drives. /s Display of de­tailed error messages. /v Filter for file attributes to limit the number of files. Can be used with the functio­nality "Search for new files". /w Filter for file names and extensions to limit the number of files. Can be used with the functio­nality "Search for new files". /?
