从excel.csv文件中删除隐藏的字符

Question

I have a large excel file containing a list of numbers (numbers.csv)

1234
1235
1236
1237

However when I use

cat numbers.csv 

it returns

1234,,
1235,,
1236,,
1237,,

I'm not sure how to fix this, but I think sed might be the right approach? relatively new to this, so trying to figure it out.

I would like generate a new file (numbers2.csv) to just contain the numbers and no ,, or other characters.

Answer 1

This should do:

sed 's/,//g' numbers.csv 
1234
1235
1236
1237

If you like to edit the original file.

sed -i 's/,//g' numbers.csv
