Question

我想匹配字符串中包含“whitespaces”和“OR”条件的bash条件。我无法做，因为我是shell脚本的新手，请帮助，因为它转到其他匹配$ {myarrlin [1]}的循环。我得到“Centrify被禁用”，但我希望条件在这里成立。这是我的代码：

FILE_CENT="/etc/nsswitch.conf" 
OS=`uname`    
if [[ $OS = 'Linux' ]]; then
 if [[ -e $FILE_CENT ]]; then
echo "nsswitch.conf found, Proceeding further..."
  while read -r LINE
  do
  if [[ $LINE =~ ^passwd ]]; then
  myarrlin=($LINE)
    if [[ ${myarrlin[1]} =~ ^(centrify)|(centrifydc)[[:space:]]* || ${myarrlin[1]} =~ [[:space:]]+(centrify)|(centrifydc)[[:space:]]* ]];  then
     echo "Centrify is enabled"
     else
     echo "Centrify is disabled"
    fi
  fi
  done < $FILE_CENT
else
echo "nsswitch.conf does not exist in $OS, cannot fetch CENTRIFY information!"
 fi 
fi

nsswitch.conf＆gt;＆gt;＆gt;

passwd:     centrify files
  or
passwd:     centrifydc files
  or
passwd:     files centrify
  or
passwd:     files centrifydc

你为什么这样做：myarrlin=($LINE)？

如果您只是想知道该行是否包含centrify：

  while read -r LINE
  do
  if [[ ${LINE} =~ ^passwd ]]; then
    if [[ ${LINE} == *"centrify"* ]];  then
     echo "Centrify is enabled"
    else
     echo "Centrify is disabled"
    fi
  fi
  done < $FILE_CENT

如何将“whitespace”和“OR”条件与bash脚本匹配？
