Remova todos os caracteres após caracteres não ASCII em todas as colunas

Question

Eu tenho um script bash que removerá todos os caracteres não Ascii do arquivo. Mas eu queria remover a string após o caractere não Ascii em todas as colunas. Abaixo está o roteiro,

> #!/bin/bash

SCRIPT_PATH=/trmout/TRMOUTPUT_PROD
BKP_PATH=/appinfprd/bi/infogix/Temp_Files/SUPPLY_CHAIN

File_Name=WB

cp $i $BKP_PATH

cat $i  >> $i.bkp

sed -i 's/[\d128-\d255]//g' $i.bkp

mv $i.bkp $i

done

Answer 1

Você quer dizer que deseja excluir qualquer coisa na linha após o primeiro caractere não-ascii? Caso contrário, forneça alguns exemplos.

Se sim, seu sed deve ser:

sed -i 's/[\d128-\d255].*$//' $i.bkp

Isso substituirá o primeiro caractere não-ascii E o restante da linha por nada.
