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
