Hi All
We're switching an existing email system to Gmail with about 25k users. Alex wrote us an excellent transfer script... but I was having problems keeping it running on the server. We would have our shell dropped automatically, yet our server loads were fine... and our memory at low %.
The problem was by not piping the script to a log file, or to /dev/null.... it was filling up the shell buffer, and dropping the shells. It was also hindered by the speed of our ISDN too, so when we piped it properly, the script sped up by 75%!
Also, if you add the & sign at the end of your script, it will run in background, and not die if you lose your shell. Isn't that sweet?
