HI,

I am trying to execute following command to save info inside a file. But it is giving error.

command:
write $FILE_NAME image lookup --address $SYMBOL_ADDRRESS

Error:
usage: write [-h] filename command [command ...]
write: error: unrecognized arguments: --address 0x100004AAC

There are a few problems with this code:

1. It should allow absolute paths. Specifically, it should not prepend ./ to the path. It should simply leave the path alone.
2. The file isn't closed.
3. When you send the output to a file, LLDB includes what it would have sent to the terminal verbatim. For a color terminal, this includes ANSI escape sequences. These should be stripped from the output.

I would have created a branch and submitted a pull request, but don't have write-permission to the repo; so here's a patch.
