Bash Script How To Manipulate Text/Strings By Searchig and Replacing Natively

  # a single first slash means first occurrence
  # format=${haystack/needle/replacement}
  # if you use a double first slash it means ALL occurrences
  # format=${haystack//needle/replacement}


  email=${file/.txt-marked/}
 

In the example above we are searching in the variable $file for ".txt-marked" and replacing with nothing (the empty part after the last / means we are replacing with nothing or actually removing it).  

How to replace all occurrences?

  email=${file//.txt-marked/}

The only difference is where the first slash goes.  If you use double slashes it means to replace ALL occurences.
