DESCRIPTION
|
||||
Computes or verifies checksums using cryptographic hash algorithms (SHA256, SHA512, SHA1, MD5, SHA384).
|
||||
Outputs hash values in standard GNU coreutils format (<hash> <filename>).
|
||||
Supports both single-dash (-o, -c, -r) and double-dash (--out, --check, --recursive) GNU-style flags.
|
||||
Supports both single-dash (-o, -c, -r) and double-dash (--outfile, --check, --recursive) GNU-style flags.
|
||||
Ignores checksum metadata files (.md5, .sha1, .sha256, .sha384, .sha512) during wildcards unless passed explicitly.
|
||||
|
||||
PARAMETERS
|
||||
-FilePath <string[]>
|
||||
Specifies the target file(s) or wildcard pattern (*).
|
||||
|
||||
-o, --out, -SaveToFile <switch>
|
||||
-o, --outfile, -OutFile <string>
|
||||
Enables auto-saving checksum results to file(s).
|
||||
- If input contains a wildcard (*), writes to 'checksums.<algo>'.
|
||||
- If an explicit file is given, writes to '<filename>.<algo>'.
|
||||
- If passed with an argument (e.g. -o custom.txt), writes to 'custom.txt'.
|
||||
- If passed with NO argument (or empty string ""), automatically outputs to 'checksums.<algo>'.
|
||||
When combined with -r and *, recursively auto-generates checksum files per directory.
|
||||
|
||||
-f, --outfile, -OutFile <string>
|
||||
Specifies an explicit destination filename for saving checksum output.
|
||||
|
||||
-c, --check, -Check <string>
|
||||
Reads hashes from a specified checksum file and verifies target files on disk.
|
||||
If -r is specified, recursively looks for and validates checksum files by name across subdirectories.

|

2. Compute SHA512 checksums recursively and auto-save (prompts for filename, hit Enter for auto):

.\checksum.ps1 * --recursive --out --algo SHA512

3. Compute SHA256 checksums and save to custom file:
|

.\checksum.ps1 * -o my_hashes.txt

4. Verify checksums against a verification file:
|
||||
.\checksum.ps1 -c checksums.sha256
|
||||
.\checksum.ps1 --check checksums.sha256
|

|

4. Recursively verify checksum files across subdirectories:

.\checksum.ps1 --check checksums.sha256 --recursive

5. Compare file directly against an expected hash string:
