Re: bash_logout and sftp

Why bother?

Why not just set a rapid rsync cron from root and rsync the entire 
structure, and move files with ownership and permission's?  If nothing has 
changed, then nothing gets moved. 

There is something to be said for simple.

rls

How disciplined are your users?  Have them create/transfer a dummy 
"/tmp/alldone" file as the last thing they do.  A periodic cron job can 
check for it and if it exists, delete it and run rsync.

Or in sshd_config, replace the sftp line with:
  Subsystem       sftp    /usr/libexec/sftp-server-rsync

And create /usr/libexec/sftp-server-rsync containing:

  #! /bin/sh
  /usr/libexec/sftp-server "$@"
  touch /tmp/alldone >/dev/null 2>&1

Modify as needed depending on where your OS puts sftp-server.  You could 
have this script run the rsync directly but you'd probably get overlapping 

rsync runs and other issues; best not to try.
