What they don't tell you about leaving UD
Step 1: give out new e-mail address
os@copland:~$ pine `echo $(grep -v '^ ' ~/.addressbook|cut -d' ' -f1)|tr ' ' ','` #note, '^ ' has 3 spaces, and -d' ' is a single tab

Step 2: get list of /tmp files on other systems (since verdi, vivaldi, haydn, and schubert aren't reachable from the outside world) and make some local tarballs
os@copland:~$ for host in strauss verdi vivaldi haydn schubert ; do ssh $host touch /tmp/`whoami`.all-files.tar ';' /opt/sfw/bin/gfind /tmp -type f -user `whoami` -print0 '|' /opt/sfw/bin/gxargs -0 -n 1024 tar rvf /tmp/`whoami`.all-files.tar -C /tmp 2>&1 | grep -v 'Permission denied' ; scp $host:/tmp/`whoami`.all-files.tar /tmp/`whoami`.all-files.$host.tar ; done

Step 3: tarball local files in /tmp
os@copland:~$ touch /tmp/`whoami`.all-files.tar ; /opt/sfw/bin/gfind /tmp -type f -user `whoami` -print0 | /opt/sfw/bin/gxargs -0 -n 1024 tar rvf /tmp/`whoami`.all-files.tar -C /tmp 2>&1 | grep -v 'Permission denied' ; bzip2 /tmp/`whoami`.all-files.tar

Step 4: transfer these files to someplace local
os@erinaceous:~$ UDEL_USERNAME=os ; scp $UDEL_USERNAME@copland.udel.edu:/tmp/$UDEL_USERNAME.all-files.tar udel-tmp-files.tar.bz2

Step 5: sync your home directory to someplace local
os@erinaceous:~$ UDEL_USERNAME=os ; rsync -P -avz -e ssh $UDEL_USERNAME@copland.udel.edu:~ udel-home

Step 6: sync your IMAP folders locally with mailsync
#!/bin/bash
# warning, this has not actually been tested, just written from my notes
# syncs IMAP folders to $HOME/mail/udel-sync/
UDEL_USERNAME=os
