Custom Configuration

Tshark, like Wireshark, uses a preferences file. A different preference file or keys can be specified with flags.

Command	Does
`tshark -C /path/to/config`	Uses custom configuration file
`tshark -o key:value`	Overrides the specified preferences key

Add Tshark Alias

Aliases allow you to define default behavior or multiple sets of behavior.

If you want to launch tshark with a custom configuration once in a blue moon, you could add an alias for it:

alias tshark-bluemoon='tshark -C BlueConfig -o BlueKey:BlueVal'

To always enable color, add a line to your .profile or .bashrc:

echo "alias tshark='tshark --color'" >> ~/.profile
