sha1sum
Calculate SHA1 cryptographic checksums. More information: https://www.gnu.org/software/coreutils/sha1sum.
- Calculate the SHA1 checksum for a file:
sha1sum {{path/to/file}}
- Calculate SHA1 checksums for multiple 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}}
- Read a file of SHA1 sums 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 for files for which verification fails, ignoring missing files:
sha1sum --ignore-missing --check --quiet {{path/to/file.sha1}}
