Remove non-ASCII characters from CSV

awk, sed

Solution

# -i (inplace)

sed -i 's/[\d128-\d255]//g' FILENAME

Problem

I want to remove all the non-ASCII characters from a file in place. I found one solution with tr, but I guess I need to write back that file after modification. I need to do it in place with relatively good performance. Any suggestions?
