What is my public IP address

Debug SSH at the Maximum Verbosity Level
When debugging an ssh connection either to optimize your settings ie compression, ciphers, or more commonly for debugging an issue connecting, this alias comes in real handy as it's not easy to remember the '-o LogLevel=DEBUG3' argument, which adds a boost of debugging info not available with -vvv alone. Especially useful are the FD info, and the setup negotiation to create a cleaner, faster connection.

Rebuild a Delimited File with a Unique Delimiter
Useful for CSV files. In the command, the file in question is comma delimited but contains double quoted fields containing commas and contains no @ symbols (as confirmed with http://www.commandlinefu.com/commands/view/9998/delimiter-hunting). This command converts the delimiting commas to @s while preserving the commas in the fields using the "uniqueString" to mark the ends of lines.
