Calculate SHA1 cryptographic checksums. More information:

  • Calculate the SHA1 checksum for one or more files:

sha1sum {{path/to/file1 path/to/file2 ...}}

  • Calculate and save the list of SHA1 checksums to a file:

sha1sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.sha1}}

  • Calculate a SHA1 checksum from stdin:

{{command}} | sha1sum

  • Read a file of SHA1 sums and filenames and verify all files have matching checksums:

sha1sum --check {{path/to/file.sha1}}

  • Only show a message for missing files or when verification fails:

sha1sum --check --quiet {{path/to/file.sha1}}

  • Only show a message when verification fails, ignoring missing files:

sha1sum --ignore-missing --check --quiet {{path/to/file.sha1}}
