You can also execute CLI commands from shell in JunOS like this:
admin@router> start shell % cli show version | grep Hostname Hostname: router %
This could be useful if you must collect some outputs and don’t want to use cut&paste from your telnet/ssh client. And it is a little bit faster, if you request bulk informations like routing tables. So this also a good choice for your scripts.
% cli show version >> log.txt % cli show route summary >> log.txt % cli show interface terse >> log.txt
