That one liner actually does what it is said to do. The -es are not needed (at least in my linux mawk). Try printing the pattern space with the l command to see how it proceeds. If it finds only zero or more <NL> (\n) chars in the pattern space which is one or more empty lines, it apends the next line. If that is empty as well, repeat. If it's the last line, quit. Any other line, print the ensemble:
I understood the logic..its was a great debugging tip to get the content of Pattern space. That was a new learning for me . But for some reason this command was not working in HP-UX without -e
Hi group,

The solution should be a one liner using awk and sed.

I have a data base of part numbers:
AAA Thing1
BBB Thing2
CCC Thing3
File one is a list of part numbers:
AAA234
BBB678
CCC2345
Is there a sed one-line that would compare a data base with and replace the part numbers so that the output looks like this?
AAA234 Thing1
