The remote copy has the same hashes? Ask the remote side, over SSH.

Quick summary

ssh runs verb-noun commands against SSH servers: compare a local folder to a remote one with md5sum, sha1sum, sha256sum (these nouns are shown in the Win64 help). libssh is required: Win64 auto-downloads the DLLs into the zpaqfranz folder. Only in the builds with SFTP, never in -DOPEN builds.

Power user usage

  • -host, -user, -password or -ssh key, -port
  • -remote the remote path

Lo spiegone

Dispatched as command J to ssh() (inside #ifdef ZPAQFULL and #ifdef SFTP).

Real-world examples

Compare with sha1, then with a wildcard

zpaqfranz ssh sha1sum d:\bak -remote /pip -host 1.2.3.4 -user k1 -password pippo
zpaqfranz ssh sha1sum d:\bak\*.txt -remote /pip/*.txt -host 1.2.3.4 -user k1 -password pippo
