Surely such utility programs exist, so I am mostly asking for your suggestions.
In a set of folders are text files. I need to search for UNDERLINE characters, and change each to TAB characters.
Ideally I'd like the operation to be recursive, so that I can use the top containing folder, and all folders within will be drilled into, finding the text files, and changing the UNDERLINE to TAB.
Additionally, the program must allow me to put in TAB. Maybe ASCII 9? Could be an issue.
