求解，文本处理sed

kaober

文本
ifeq ($(strip $(PROJECT_A680)), yes)
export PROJECT_BUILD_VER=V01
export BUILD_ID=A680
else ifeq ($(strip $(PROJECT_C100)), yes)
export PROJECT_BUILD_VER=V01
export BUILD_ID=C100
else ifeq ($(strip $(PROJECT_M709)), yes)
。。。。。。。。。。。

现在想对每个export PROJECT_BUILD_VER=V后面的数字自加1. 现在see匹配后怎么嵌入运算呢？

sed "s/PROJECT_BUILD_VER=V\([0-9]*\)/PROJECT_BUILD_VER=V\1/g" $build_id_file

\1 进行自加1？

用awk吧，骚年~

/e

expr \1 + 1/e

此外，这个似乎没办法做的，因为计算容易，比如
ab3
sed会替换为ab 3+1然后bash执行的是ab 3+1,结果是command not found

awk似乎是不二之选了。

只会用awk

1. awk '/PROJECT_BUILD_VER/{s=gensub(/(.*V0*)([0-9]*)/,"\\1",1);v=gensub(/(.*V0*)([0-9]*)/,"\\2",1);++v;$0=s""v}1' i
   
2. ifeq ($(strip $(PROJECT_A680)), yes)
   
3. export PROJECT_BUILD_VER=V02
   
4. export BUILD_ID=A680
   
5. else ifeq ($(strip $(PROJECT_C100)), yes)
   
6. export PROJECT_BUILD_VER=V02
   
7. export BUILD_ID=C100
   
8. else ifeq ($(strip $(PROJECT_M709)), yes)

1. awk -F"=V" '/export PROJECT_BUILD_VER/{$1 FS $2+1;next}{print $0}'

How about this way

$ perl -lape 's/(PROJECT_BUILD_VER=V)(\d+)/sprintf("%s%02d",$1,$2+1)/ge' FILE
ifeq ($(strip $(PROJECT_A680)), yes)
export PROJECT_BUILD_VER=V02
export BUILD_ID=A680
else ifeq ($(strip $(PROJECT_C100)), yes)
export PROJECT_BUILD_VER=V02
export BUILD_ID=C100
else ifeq ($(strip $(PROJECT_M709)), yes)

谢谢，
再问问最后那个1的意思是什么？不写貌似没有输出。

打印当前行，相当于 true{print $0}
