I am not sure what would be simpler than "sh lo ch" versus "sh lo". In EXOS, there is no customization of default behavior of cli output, other than scripting. That having been said, there is a simpler method if you are automating your output.
You can write whatever commands you choose in any way you choose in an .xsf file and then just run it. This function only outputs to console by default.
The python method is really quite simple as well. Simply do:
vi shloch.py
i
print exsh.clicmd('show log chronological', True)
:wq
run script shloch.py
and enjoy!
