Just want to understand how awk redirection to a file based on field value works.

Have below command in one of the script which is creating files with 3rd field as names and entries only with their respective values(which is as per requirement), but unable to understand how it works

Also is it possible to create the output with only field 1 in output.

Tried checking o reilly book for output redirection but didn't get a clue.

command

awk '{print >> ( $3 ".txt")}' filename

Input file

test jfk 20190425

sampletext2 est 20190426

text1 happy 20190425

text2   text4 20190424
