I have a file which contains data as below, there is 2 keywords, current_area {data1/data2/code..}, current_area {data1} and some data between those:

current_area {data1/data2/codeA..}

do_this {data}

do_this {data}

current_area {data1}

current_area {data1/data2/codeB..}

do_this {dataX}

do_this {dataY}

current_area {data1}

I want to arrange it such that for all the “do_this” between their set of current_area {data1/data2/code..} and current_area {data1} have the code part come in do_this, like :

current_area {data1/data2/codeA..}

do_this {codeA../data}

do_this {codeA../data}

current_area {data1}

current_area {data1/data2/codeB..}

do_this {codeB../data}

do_this {codeB../data}

current_area {data1}

I have tried with sed but I am lost on the algo here.

I thought to replace the current_area with do_this only.

sed ‘s@current_area {data1/data2/@do_this {‘ file, but that only makes the whole file with do_this
