How to capitalize and replace characters in shell script in one echo

I am trying to find a way to capitalize and replace dashes of a string in one echo. I do not have the ability to use multiple lines for reassigning the string value.

For example: string='test-e2e-uber' needs to echo $string as TEST_E2E_UBER

I currently can do one or the other by utilizing

${string^^} for capitalization

${string//-/_} for replacement

However, when I try to combine them it does not appear to work (bad substitution error). Is there a correct syntax to achieve this?

echo ${string^^//-/_}

Solution

  • This does not answer directly your question, but still following script achieves what you wanted :

    declare -u string='test-e2e-uber'
echo ${string//-/_}
