> Calculate SHA1 cryptographic checksums.
|
|
|
|
- Calculate the SHA1 checksum for file(s) or files in a directory, one checksum per file:
|
|
|
|
`sha1sum {{filename1}}`
|
|
`sha1sum {{filename1}} {{filename2}}`
|
|
`sha1sum {{directory/\*}}`
|
|
|
|
- Read a file of SHA1 sums and verify all files have matching checksums:
|
|
|
|
`sha1sum -c {{filename.sha1}}`
