Skip awk, use perl....
The alias below sets perl to loop over STDIN splitting each line on more than one whitespace character and populate an array F. The -nE will then Evaluate an expression from the command line looping over the input line-by-line.
alias glorp='perl -aF"/\s+/" -nE'
So now we have the command `glorp` to play with which has more familiar syntax than awk and all of CPAN available to play with!
$ [data is generated] | glorp '/Something/ and say $F[2]'
We have access to any Perl module by putting -MModule::Name=function after the command, the following will parse a JSON record per line and glorp out what we wanted:
$ echo -e '{"hello":"world"}\n{"hello":"cat"}' | glorp 'say decode_json($_)->{hello};' -MJSON=decode_json
world
cat
Maybe you are used to using curl too. There is a nice web framework in Perl called Mojolicious (
http://mojolicious.org) that provides a convenience module called 'ojo' for command line use. So grabbing the summary sentence from Wikipedia articles is as straight forward as below. Notice Mojolicious lets us use CSS selectors!
$ echo -e 'grep\nawk\nperl' \
| glorp 'say g("wikipedia.org/wiki/$F[0]")->dom->at("#mw-content-text > div > p")->all_text' -Mojo
