Question

在File Test1.jmx中，我需要将字符串值替换为false，其中value = true或0或null。我需要对文件中出现的所有字符串执行此操作。

before:
<boolProp name="ThreadGroup.scheduler">true</boolProp>
after:
<boolProp name="ThreadGroup.scheduler">false</boolProp>

这是我错误的代码：

overrides_scheduler="BLAAA FOO MOO"
overRides=$(awk -v newValue="$overrides_scheduler" '$0 ~ /boolProp name="ThreadGroup.scheduler"/ {a=$0; sub(/<boolProp name="ThreadGroup.scheduler">[a-zA-Z0-9]/,"<boolProp name=\"ThreadGroup.scheduler\">"newValue,a); print a; next;}{}1' "Test1.jmx");
echo  "$overRides" > "Test1.jmx"

Test1.jmx：

<boolProp name="ThreadGroup.scheduler">true</boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">true</boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">true</boolProp>
<boolProp name="ThreadGroup.scheduler"></boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">0</boolProp>

Answer 1

使用GNU sed：

sed -r 's|(<boolProp name="ThreadGroup.scheduler">)(true\|0\|null)(</boolProp>)|\1false\3|' Test1.jmx

输出：

<boolProp name="ThreadGroup.scheduler">false</boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">false</boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">false</boolProp>
<boolProp name="ThreadGroup.scheduler"></boolProp>
<longProp name="ThreadGroup.end_time">1363247040000</longProp>
<boolProp name="ThreadGroup.scheduler">false</boolProp>

Answer 2

我设法做了以下事情：

echo '<boolProp name="ThreadGroup.scheduler">true</boolProp>' | awk -F'\">|</' '/ThreadedGroup.scheduler/ {sub(/true/,"false");print}'

也可以与cat一起使用或将文件名放在命令的末尾。
