如何使用脚本增加浮点数的构建数字

Question

大家好，我尝试了以下方式，但它们都没有帮助我在命令行上没有任何错误。

我当前的构建号是1.4.0，我想获得1.5.0 ..

获取捆绑版本并从info.plist文件构建版本值

BUNDLE_VERSION=$(/usr/libexec/PlistBuddy -c "Print:CFBundleShortVersionString" <my plist path>)
BUILD_NUMBER=$(/usr/libexec/PlistBuddy -c "Print :CFBundleShortVersionString" <my plist path>)

将构建数量增加一个

#BUILD_NUMBER=`echo $BUILD_NUMBER +1|bc` //have tried this one first but didnt work
BUILD_NUMBER=$((BUILD_NUMBER+=1)) //that one also didnt help

有什么想法？

Answer 1

BUILD_NUMBER=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" <my plist path>)
echo $BUILD_NUMBER

将构建数量增加一个

NEWSUBVERSION=`echo $BUILD_NUMBER | awk -F "." '{print $3}'`
NEWSUBVERSION=$(($NEWSUBVERSION + 1))
NEWVERSIONSTRING=`echo $BUILD_NUMBER | awk -F "." '{print $1 "." $2 ".'$NEWSUBVERSION'" }'`
echo $NEWVERSIONSTRING

在主项目中更新信息中的构建号

/usr/libexec/PlistBuddy -c "Set :CFBundleVersion ${NEWVERSIONSTRING}" <my plist path>
