Or maybe something like this in perl itself?
perl -ne 'print @{[split(/\s+/,)]}[-1],qq(\n);' file

I wouldn't use a slice at all:

Great idea! In Windows, I used
gawk {print $NF} file
Thanks.

In the one- and two-argument forms of the call, the mode and
filename should be concatenated (in that order), preferably
separated by white space.

Hi. List Mom here.
Please take this off list, it's not on-topic.
John: Thank you for answering the OP's question. However, Shlomi is
right, the two argument form of open() is something that the general
Perl community considers to be a deprecated style that should not be
used with new code. This

This is irrelevant. Two-args open is dangerous - always use three-args open:

You were asked to take this off list once.
I'm now telling you, in my official capacity as list moderator:
further discussion of this is off-topic and does not belong on this
list.
Let it go.
thanks,

I apologize for having to ask this but my nearly-80-year-old brain just
could not come up with a solution.
I have a text file consisting of several space-separated fields:
lastname firstname other other other ... emailaddress
I wish to write a new file that contains only the emailaddress field
You can try the following regexp:
.*([^ ]+@.*)$
This assumes that the email address is the last string and all strings are
space separated.
