mongoexport and mongoimport with query from one host to one host

I would like to query the data that I need only from a server to another server, and I just use one line of command in linux shell

mongoexport -h -d fromDB -c fromCollection -q '{ count: { $gte: 1 } }' | mongoimport -h -d toNewDB -c toNewCollection

If your date is many GB, you can run it in background using nohup

nohup "mongoexport -h -d fromDB -c fromCollection -q '{ count: { \$gte: 1 } }' | mongoimport -h -d toNewDB -c toNewCollection" &

If you want to view the current process

tail nohup.out -f

It will output something like
