Mirrordir is a suite of functions in one package. It contains the following programs: * pslogin: A remote login utility and daemon that provides a secure shell. This can be considered as a GPL replacement to Ssh. * copydir: A cp equivalent which additionally copies to and from ftp servers. Use it to upload and download via ftp and via mirrordir's secure daemon. Use it as a rigorous cp to correctly reproduce hardlinks, permissions and access times. * mirrordir: Mirrors filesystems over ftp or locally via a minimal set of changes. It is optimised for locally mirroring a device as an alternative to RAID devices. It duplicates file-systems in every detail, even correctly recreating hardlinks, devices and access times. It works well mirroring ftp sites that don't support ls-lR summaries. Mirrordir can take a C script to customise the kind of files to mirror based on their stat info, name, or other information. * recursdir: Pass a C script to recursdir to recursively perform operations on files. This is a fast and overkill equivalent of find.
