# Use

Bash Base64, written in C++.

Uses a custom Base64 character set for bash compatibility, not compatible with other utilities.

```
Usage:
    bb64 BASE64COMMAND          Decodes and runs the command
    bb64 -[i|d] BASE64COMMAND   Displays the decoded command
    bb64 -e COMMAND             Encodes the command and prints the result
    bb64 -u                     Updates bb64 to the latest version (uses docker)
```

# Implementation Notes

bb64 runs the command by replacing the current process, so it ensures that tty, environment
variables etc are all identical for the run command. It works with interactive commands, like
nano or ssh.

bb64 supports bash scripts, as the command is run as:
    `bash -c 'COMMAND'`
Where COMMAND is passed to bash as a single argument.

If the command is run, the return value is the return value of the command.
If it isn't run, bb64 returns -1.
