You can use

if [[ "${CI_COMMIT_BRANCH}" =~ feature/ ]];
  echo "Feature Branch Found !"
else
  echo "Production Branch Not Found !"  
fi;

Note:

  • There must be spaces after [[ and before ]]
  • The .* in your case is redundant and can be removed (it just matches the rest of the string, and since you are not capturing the data and not using it later, this is not necessary)
  • It is always a good idea to quote your string variables, "${CI_COMMIT_BRANCH}".
