How to remove New line character from batch variable

Question

Good Day All! I have a batch script, and when I echo a variable like this

echo %variable1%

I get out put like this

TestLine1
TestLine2
TestLine3
TestLine4

My goal would be to modify this variable to remove all the newline characters so the output would look more like

TestLine1TestLine2TestLine3TestLine4

Is there a simple way to do this without creating files? Thank you for your assistance.

您可以使用命令tr：

cleanedVariable1=$(echo $variable1 | tr -d '\n' )
echo $cleanedVariable1

命令 tr 删除或翻译字符。选项 -d 删除给定的字符。在这种情况下，我们将从变量中删除所有新行并将其分配给一个新变量。
