# md5sum
|
|
|
|
> Calculate MD5 cryptographic checksums.
|
|
> More information: <https://www.gnu.org/software/coreutils/md5sum>.
|
|
|
|
- Calculate the MD5 checksum for one or more files:
|
|
|
|
`md5sum {{path/to/file1 path/to/file2 ...}}`
|
|
|
|
- Calculate and save the list of MD5 checksums to a file:
|
|
|
|
`md5sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.md5}}`
|
|
|
|
- Calculate an MD5 checksum from `stdin`:
|
|
|
|
`{{command}} | md5sum`
|
|
|
|
- Read a file of MD5 sums and filenames and verify all files have matching checksums:
|
|
|
|
`md5sum --check {{path/to/file.md5}}`
|
|
|
|
- Only show a message for missing files or when verification fails:
|
|
|
|
`md5sum --check --quiet {{path/to/file.md5}}`
|
|
|
|
- Only show a message when verification fails, ignoring missing files:
|
|
|
|
`md5sum --ignore-missing --check --quiet {{path/to/file.md5}}`
