Unexpected exit

I'm running this command to remove repeated lines from a file: 

cat arquivo.csv | (read;echo "$REPLY"; sort) | uniq > arquivo.csv

But when I look at the file, it is blank rather than just the lines that do not repeat themselves. What am I doing wrong?

You can do this by using the sort. 

sort -u arquivo.csv -o arquivo.csv
  • -u will remove duplicate lines
  • -o will send the output to the .csv file

You can use the command: 

cat arquivo.csv | sort | uniq > novoArquivo.csv
