Make your LLDB experience 26% better* with one weird trick: pipe the output of lldb commands to any normal shell command.
(lldb) command script import /path/to/lldbsh.py
(lldb) sh image list | wc -c
3898
(lldb) sh env | grep SDKROOT
SDKROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
Pagers are also supported! (but, as yet, the subprocess is not killable):
(lldb) sh image list | less
...
* does not improve symbolication speed :(
