  • It is. Since the OP said that there is a unique TAB in between the "word" and the rest of the data. Mind the FS definition! Commented Apr 1, 2015 at 9:31
  • No. I assign the whole $0 (which contains the TAB) to out. Commented Apr 1, 2015 at 9:36
  • The two comments from me look a bit strange now because the one to whom I was replying to deleted his comments. To summarize; the essence is that the presented solution considers all requirements (including to keep data and TAB-separators intact). - That said; I wonder why there was (besides the upvote) also a downvote. Would the voter please add a rationale for that. Commented Apr 1, 2015 at 10:17
  • Seems to be the shortest, but for some reason it fails on many lines. Perhaps because the file contains a lot of utf-8 special characters? Commented Apr 1, 2015 at 10:19
  • With a not too old GNU awk you'd have UTF-8 supported. Is your locale appropriately set? (Something like LC_ALL=en_US.UTF-8.) Otherwise it would be helpful to get some of the sample lines where you see problems; it could also be that the data format is not everywhere as you expected it. Your feedback is appreciated, to track where in the chain of processing the problem lies; somewhere a fix will be necessary. Commented Apr 1, 2015 at 10:27
