Clear CLI with 1000 blank lines

For when you really want older output way out of your way, e.g., debugging, copying/pasting.

1. for i in {1..1000};do echo;done

bash: funky hostname expansion in for loop

1. for host in myhosts-{2{2,{6..9}},3{2,5,{7..9}}}.mydomain.com
1. do 
1. echo $host
2. echo "ssh $host cmd"
2. done

Double looping with bash

Neat:

1. for ITEM in $(find /cassandra/data -type d -name snapshots)
1. do for DIR in $(find ${ITEM} -maxdepth 1 -mindepth 1 -type d -mtime -1)
1. do echo $ITEM $DIR
2. done
2. done
