一开始就想到了expect，但好像不适合，就没再继续！
java版本操作基本也写好了，但非常纠结的想用shell来做操作mongo,就是执行mongo shell命令，如db.foo.find(),db.foo.remove({date:"2012-09-18"})的操作，想了半天还是没想出来，不知各位是如何处理的

在发帖时，突然想起来了python，哈哈......

mongo [options] [db address] [file names (ending in .js)]
比如
mongo --host 127.0.0.1:27017 testdb remove.js
remove.js内容：
db.foo.remove({date:"2012-09-18"})

THX，谢了！
那就好办了，批量生成js，再来执行mongo

P.S.
我用python又写了遍

/data0/mongodb/bin/mongo 127.0.0.1:27015/admin /data0/mongodb/backup.js 1>>/data0/cron_backup.log 2>>&1

cat /data0/mongodb/backup.js
base = "/data0/backup/"
function showdate(n) {
var uom = new Date(new Date()-0+n*86400000);
uom = uom.getFullYear() + "-" + (uom.getMonth()+1) + "-" + uom.getDate();
return uom;
}
db.runCommand({fsync:1,lock:1})
runProgram("cp","-ar","/data0/mongodb/data",base+showdate(0))
db.$cmd.sys.unlock.findOne()
removeFile(base+showdate(-8))
