When I start jw on ubuntu64 and run the following:
'a b c' =. 2!:2 '/usr/bin/perl -n -e ' "print" '
the j session vanishes.

Where can I find examples of using 2!:2?
(I've tried the FindInFiles but I didnt find anything useful).

In perl I can use a pipe as if were an input file - (for example):
open F, 'cat inputfile | tr -d "7Z" |";
@wholefile = <F>;  # the variable @wholefile will contain either 7 or Z

Would I use 2!:2 to do something similar?

Thanks in advance.
