Citat:

Ursprungligen postat av xiaojesus Hej alla Jag har ett manus, men jag skränande lägga upp den sammanfattande rapporten .. hålla med synax fel. åtanke att hjälpa mig att ta en titt och berätta vad som gick fel .. Jag vet är lite lång, men jag hoppas någon kan Hep mig med det. tack felmeddelandet kommer upp när jag försöker köra den sammanfattande rapporten ..

Vilket fel får du?

Är det: typ: invalid option - 4

# Global variables
POS=~/.Point_Of_Sales
POS=POS.txt

Du är anvisa två olika värden för POS, bara de senaste uppdraget varar, och det första kan lika gärna aldrig har gjorts.

export POS

confirm()
{
  echo -en "$@"
  read ans
  ans=`echo $ans | tr '[a-z]' '[A-Z]'`
  if [ "$ans" == "Y" ]; then
    return 0
  else
    return 1
  fi
}

Undvik alternativ till eko, de är icke-standard som är \u003d\u003d.

Du behöver inte ringa tr, kan du kontrollera svaret utan den:

Kod:

confirm()
{
  printf "%s " "$*"
  read ans
  case "$ans" in
    [Yy]) true ;;
    *) false ;;
  esac
}

Nej, inte om du inte svarar på de frågor du har ställt.
