The common method at this time is to copy out the column, put it in the text, and replace it with a regular expression:

Vim a.txt:%s/\ nUniverse Magazine WQ

But when it comes to a batch of files that need to be handled in this way, it's too cumbersome to open a vim. Naturally, I thought of sending the command s /\ nUniverse to each file for execution. After a search, the sed command came into sight. But tools like sed,awk are line-oriented, so at first

Sed's /\ nCompact'* .txt
