Usage
Since sic uses stdin and stdout as its user interfaces, it is easy to combine it with other tools if you need more features.
See also the sic(1) man page.
History
If you want to store what is being said, you can use the tee(1) command with sic:
$ sic | tee -a sic_history
Highlighting
If you want to receive an alert in case someone mention your username, you can use awk(1):
$ sic | awk '/username/ {printf "\a"}1'
Using a tool like awk(1) would allow you to be highlighted on specific channels for example. You can of course combine it with the tee(1) command above:
$ sic | tee -a sic_history | awk '/username/ {printf "\a"}1'
