Renaming a file without overwiting an existing file name
Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file! The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.

AWS Route53 hosted zone export
Frustrated with the manual domain migration process AWS has, I unsuccessfully tried to install cli53, route53-transfer. I instead wrote this oneliner to ease the export (which is not supported via the AWS console ATM). The output can be easily pasted into the "Import Hosted Zone" dialog in Route53. SOA/NS records are excluded since they cannot be automatically imported.
