Hi,
suppose the input data are saved in the file x.
Then this little command line could help:
perl -e 'while (<>) {/thing|hello/ && print}'<x
resp. create an executable file thing.pl with 2 lines
#!/usr/bin/perl
while (<>) {/thing|hello/ && print}
and call
thing.pl <x
or
cat x|./thing.pl
This is you needed?
Kind regards
