Hi Niels, Believe it or not, still no luck. When I run the command you gave to verify after performing the fix, the output is no different than when I ran “file” prior to the fix. Here’s the commands and output I ran, directly copy-pasted from terminal. benchernoffsmbp:Raw_FA bchernof$ file design.txt design.txt: ASCII text benchernoffsmbp:Raw_FA bchernof$ tr -d '\r' < design.txt > design_fixed.txt benchernoffsmbp:Raw_FA bchernof$ file design_fixed.txt design_fixed.txt: ASCII text As you can see, the output is “ASCII text” both times. Not sure if this would make a difference but here’s my system info: Mac OS 10.12.5. For bash: GNU bash, version 3.2.57(1)-release (x86_64-apply-darwin16) It would be great if I could create these text files correctly from the start, because I will inevitably be using sever. If the data need to be copy pasted because there are a large number of rows, what is the optimal program to copy from (excel, MATLAB, etc.) if it matters, and then once in plain-text format in text-edit, which encoding should I select when I save it?
