Question

我有很多文件夹patch_data.conf。

我创建了这个脚本：

#!/bin/bash    
Directory=~/MIUI_developer
stringreplace="include "/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch";"
stringnew="#include "/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch";"

sudo find $Directory -type f -name "patch_data.conf" -exec sed -i 's/$stringreplace/$stringnew/g' {} \;

启动此命令时，我得到此输出：

sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'

sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'
sed: -e expression #1, char 20: unknown option to `s'

我该如何解决？

Answer 1

使用：

,

注意＆＃34; /＆＃34;而不是＆＃34; {}＆＃34;，双引号和＆＃34; stringreplace="include \"/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch\";" stringnew="#include \"/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch\";"＆＃34;在sed调用中的变量扩展中。

修改：

为了使其与您的数据一起使用，需要在字符串中添加空格键（在＆＃34; include＆＃34;之后）：

#!/bin/bash Directory=./MIUI_developer stringreplace="include \"/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch\";" stringnew="#include \"/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch\";" find $Directory -type f -name "patch_data.conf" -exec sed -i "s,${stringreplace},${stringnew},g" {} \;

<强> EDIT2 ：

完整脚本：

./MIUI_developer/patch_data.conf

include "/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch";文件的关键行：

< #include "/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch"; --- > include "/home/miui-tool/Patches_jbart/MIUI_9/patches/Weather/Weather.ptch";

运行脚本后，创建文件的差异为：

{{1}}

因此，您会看到该行不已删除，并且会引入您想要的替换。

Answer 2

shell处理变量扩展。当您使用单引号时，shell会逐字地解释内容。要在执行sed之前让shell扩展变量，您需要将变量用双引号括起来。

protected void DropDownList1_SelectedIndexChanged1(object sender, EventArgs e)
{
  TextBox1.Text = DropDownList1.SelectedItem.Text
}

将sed应用于多个文件
