Thank you, I was looking for something like this. While it worked for 'tcpdump', it didn't for taking UCS archive via CLI.

(tmos)# save /sys ucs  $HOSTNAME
Error, invalid characters in UCS file name. The dash, period, forward-slash, plus sign, and underscore are the only special characters allowed.

Unexpected Error: UCS saving process failed.

    # tmsh save /sys ucs $HOSTNAME-$(date +%Y%m%d%H%M)
