[SOLVED] efficient use of sed in replacing non zero with true and zero with false

Issue

Team, i have a file that looks for non zero and replaces with FALSE and 0 with TRUE. am doing it like this

sample input text

branch="false" hits="0" lineNumber="36"
branch="false" hits="1" lineNumber="36"
branch="false" hits="2" lineNumber="36"
branch="false" hits="211" lineNumber="36"
branch="false" hits="411" lineNumber="36"

sed -i   '/<line/s/hits="0"/hits="false"/g' $coverage_file
sed -i   '/<line/s/hits="1"/hits="true"/g' $coverage_file
sed -i   '/<line/s/hits="2"/hits="true"/g' $coverage_file
sed -i   '/<line/s/hits="3"/hits="true"/g' $coverage_file

can i combine all these in less operations?

expected outout

branch="false" hists="false" lineNumber="36"
branch="false" hits="true" lineNumber="36"
branch="false" hits="true" lineNumber="36"
branch="false" hits="true" lineNumber="36"
branch="false" hits="true" lineNumber="36"

Solution

You could shorten along these lines:

sed -E -i '
    /<line/ {
        s/(hits=")0"/\1false"/g
        s/(hits=")[^"]*[1-9][^"]*"/\1true"/g
    }
' "$coverage_file"

This calls sed just once, combines the conditions for "true", and uses capture groups.
