I have 200+ large files that all have exactly 1 column and 76M rows. I want to start a newfile.txt and slap the columns next to each other (match Line 1 of File 1 with Line 1 of File 2... and continue adding until Line 1 of 200). Then repeat this for all rows. I am struggling with this. Any suggestions?
I have tried Gilles and Glens answers here and here but I can't figure out how to loop and repeatedly add tab-delimited columns to the output newfile.txt. I can only use methods that do not store the files in memory (the final file should be 120GB+).
