Question

我正在尝试检查两个条件是否都返回预期值。我想确保在继续之前返回预期值... 我有问题的一行是：if [ [ $ansmob = "y" ] || [ $flagbook != "1" ] ];

read -r -p "Would you like to add $site.booking.local as well? [y/n] " ansbook
        if [ $ansbook = "y" ];
                then sed "s/ServerAlias.*/& $site.booking.local/" -i $workdir/$site$dom.conf
                flagbook="1"
        fi
read -r -p "Would you like to add m.$site.booking.local? [y/n] " ansmob
        if [ [ $ansmob = "y" ] || [ $flagbook != "1" ] ];
                then sed "s/& $site.booking.local/& $site.booking.local m.$site.booking.local/" -i $workdir/$site$dom.conf
                else
                sed "s/ServerAlias.* /& m.$site.booking.local/" -i $workdir/$site$dom.conf
                flagmobile="1"
        fi

Answer 1

替换

if [ [ $ansmob = "y" ] || [ $flagbook != "1" ] ];

与

if [ "$ansmob" = "y" ] || [ "$flagbook" != "1" ]

Answer 2

使用bash的双括号，您可以使用&&和||

if [[ $ansmob = "y" || $flagbook -ne 1 ]]

在双括号内，引用变量并不是绝对必要的：这个命令很聪明地评估带有空变量的表达式。

二进制＆amp;＆amp; operator是AND操作的语法。

如何在脚本中使用条件'和'条件？
