Trying to import 53,800+ individual files (messages) using Gmail's POP fetcher.
Gmail understandably refuses, giving the error: "Too many messages to download. There are too many messages on the other server."
The folder in question looks like similar to:
/usr/home/customer/Maildir/cur/1203672790.V57I586f04M867101.mail.net:2,S
/usr/home/customer/Maildir/cur/1203676329.V57I586f22M520117.mail.net:2,S
/usr/home/customer/Maildir/cur/1203677194.V57I586f26M688004.mail.net:2,S
/usr/home/customer/Maildir/cur/1203679158.V57I586f2bM182864.mail.net:2,S
/usr/home/customer/Maildir/cur/1203680493.V57I586f33M740378.mail.net:2,S
/usr/home/customer/Maildir/cur/1203685837.V57I586f0bM835200.mail.net:2,S
/usr/home/customer/Maildir/cur/1203687920.V57I586f65M995884.mail.net:2,S
...
Using the shell (tcsh, sh, etc. on FreeBSD), what one-line command can I type to split this directory full of files into separate folders so Gmail only sees 1000 messages at a time? Something with find or ls | xargs mv maybe. Whatever is fastest.
The desired output directory would now look something like:
/usr/home/customer/Maildir/cur/1203672790.V57I586f04M867101.mail.net:2,S
/usr/home/customer/Maildir/cur/1203676329.V57I586f22M520117.mail.net:2,S
...
/usr/home/customer/set1/ (contains messages 1-1000)
/usr/home/customer/set2/ (contains messages 1001-2000)
/usr/home/customer/set3/ (etc.)
Ideally, cron could run another command to automatically reverse the process in 1000 message increments every hour. So Gmail only sees & downloads 1000 at a time.
