In Windows, from a Shell you can type in 'start' to open another shell instance. What is the equivalent command in OS X?
Here is a way to start a command (in my case
tail ing a log file) and keep it running:
echo "tail -n 70 -f /tmp/livy.log" >> /tmp/xyz && chmod u+x /tmp/xyz && open -a /Applications/utilities/Terminal.app /tmp/xyz
I suppose something similar might be done for keeping a general purpose bash prompt around - along the lines of
bash -c <some command>
