CUT command is only processing the first line

I am trying to cut the first 10 columns of a csv file that has about 30 million lines.

My command is:
cut -d "," -f 11- data.txt>cutdata.txt

Open in new window

It only processes the first line. It runs  for a while, and it does write out the new file, but with only the first line cut properly.

If I take only the first 100 or so lines of the data.txt and use the same cut command, it works perfectly.

Can this be done with sed or awk? If so, can you provide the exact syntax?

My first impression is that your original file has line endings different from what the cut command expects, while your extract  differs in this respect so the cut command works on it just fine.

This is awk:

awk  -F, '{for(n=11;n<NF;n++) {printf "%s,",$n} print $NF}' data.txt > cutdata.txt

No idea why "cut" shouldn't work, though. Maybe it's a temp space or buffer handling issue.
Does the concerned filesystem have enough space to hold the output file?
Can you try other lengths between 100 and 30 million lines to find exactly where it starts to fail?
Does it make any difference if you do
cut -d "," -f 11- <data.txt>cutdata.txt
