Changes

1. Initial Version

3. now do excludes while scanning...faster
4. keep track of local date
5. fix bug with new directories, new files and deleted files

Installation

Notes

jFtpMirror sends only those files that have changed since the last time the utility was run. It uses FTP as the transport mechanism.

It now supports the following commands:

sync	update db to the remote site and then send any differences
update	db to remote site
sendonly	assume the db is up-to-date and send any differences
diff	display differences between db contents versus the local directory (no connection required)
convert	converts all line endings to unix style without sending files (no connection required)

and some other options:

vv	very verbose output
v	verbose output
q	quiet (no output)
unix	converts all line endings to unix style for any sent files
force	send all files (consider all files as changed)

Enhancements

• It does not set permissions on remote files. Don't know if FTP has this capability.
• For crlf -> lf conversions, there needs to be an exclusion list (e.g. exclude .exe's, .zips, etc.). Again some doubt this functionality belongs in jftpmirror
• If the transfer is aborted (e.g. by ctrl-C), the contents of the database file (xx.webmirror) is suspect. Perhaps I should auto-detect and auto-correct?
• if an exclude pattern is given for the remote site, should it automatically apply to the local site?
• if there are only files that match excluded patterns in a deleted directory, do we still delete the directory?
• need to allow a response file (e.g. '@file')

Known Bugs

• if the remote file is changed, but the size remains the same, no difference is detected.
• if a remote directory is excluded, still scans the contents
