How to merge .CSV files in macOS Terminal
Heads up!
Make 100% sure that you’re entering the command in the right folder.
You don’t want ALL .csv files in your entire computer be altered this way now do you?
Code first, text later. Simply use this in the terminal:
cat *.csv >merged.csv

The code you see above: that's it.
Translated, it says: 'take all files in this folder that end with '.csv', and put them in 'merged.csv' (effectively merging them).
