in thread repeat data at one line and grep as pre-set format

cat yourfile.txt | perl -ple 's/(\S+\s+\S+)\s+/$1\n/g'

Isn't that the same as:

perl -ple 's/(\S+\s+\S+)\s+/$1\n/g' yourfile.txt

UUOC.

You are right and your way is more efficient too. I wrote it with the cat file | as that is how I tested it with echo, just failed to engage my brain completely :-)
