In bash, how do I use grep to find a certain function from the output of perldoc? -

-

so want find built in function perl. running ubuntu, run line in terminal:

$ perldoc perlfunc | grep "map"

but don't documentation function, using grep wrong?

grep finds individual lines, won't much.

use e.g.

perldoc -f map

to see doc given built-in.

(and perldoc perldoc see doc perldoc.)
