--- title: "Interactive String Substitution" tags: [ "data", "vim", "substitution" ] --- Want to find and replace, but also confirm each instance? ```sh vim -c "%s/${pattern}/${replacement}/gc" -c 'wq' ${file} ``` Notice that double-quotes (`"`) in the first command (`-c`). Alternatively, check with an example string: ```sh sed "s/${pattern}/ARGLEBARGLE/g" ${file} | grep 'ARGLEBARGLE' ```
