You can temporarily change the preferences for columns to display using 
the -o option.  To display only the info column, try this (the first is 
the title of the column, which tshark doesn't display and the second 
value is the code to use [see below]):

  tshark -o column.format:"Info","%i"

The syntax is taken from the preferences file (on Unix, 
~/.wireshark/preferences and on Windows, check the Folders tab in 
Help->About and look for global configuration) and you can find all of 
the % codes for columns from epan/column.c in the source code
