fastest way convert tab-delimited file to csv in linux

Question

I have a tab-delimited file that has over 200 million lines. What\'s the fastest way in linux to convert this to a csv file? This file does have multiple lines of header i

Answer 1

I think it is better not to cat the file because it may create problem in the case of large file. The better way may be

$ tr ',' '\t' < csvfile.csv > tabdelimitedFile.txt

The command will get input from csvfile.csv and store the result as tab seperated in tabdelimitedFile.txt
