sed - replacement group in command line double quoted

  • 772

I am trying to run this

sed -i -e "s/'(\${RConstants\.staticPath}\/dist\/img\/app\/icons\.svg#[a-z_-]*)'/`\1`/g" test

Single quote version

sed -i -e 's/'\''(\${RConstants\.staticPath}\/dist\/img\/app\/icons\.svg#[a-z_-]*)'\''/`$1`/g' test

Content of test file:

useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');    useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');
    useElem.setAttributeNS(null, 'href', '${RConstants.staticPath}/dist/img/app/icons.svg#rsvg__ui--play');

Basically I need to replace single quote with back tick.

The problem is that I tried doing the sed command with single quotes and with double quotes, each having its own problem.

With double quotes, I'm getting 1: command not found and with single quotes, it doesn't replace anything.

command-line bash sed

  1. Problems were 2:

    Unescaped backticks (Those are used to spawn a new process) Unescaped parenthesis, so after fixing the backticks, the error was about not having a capture group.

    sed -i -e "s/'\(\${RConstants\.staticPath}\/dist\/img\/app\/icons\.svg#[a-z_-]*\)'/\`\1\`/g" test

    So this worked OK.
