You can use infocmp -L -1 to print out a terminfo entry for current TERM.

I'm not sure of an equivalent for termcap but termcap is readable plain text (if you know it's capability codes). I guess you could make use of captoinfo in conjunction with infocmp

To be clear: Just infocmp also works (the -I −1 option formats it with one capability per line). –  Chris Page Jul 4 '12 at 2:10
@ChrisPage: Good point. Actually I meant to write -L not -I, which gives longer names that are easier to understand if you are unfamiliar with terminfo capability names. The -1 aids readability. –  RedGrittyBrick Jul 4 '12 at 8:41
