I use Sublime Text 3 text editor for viewing and editing files. Sublime Text offers various features. There is one important and useful feature - You can search and select multiple instances at one and replace them with a different text. For example, if you have text "-test" in multiple places in the document and if you want to replace the text with "-prod" at once for all the selected instances, then here are simple steps: Open the document in Sublime Text Select any string in the document, for my example I am selecting "-test" Now press: MAC: Command + Control + G Windows: Alt + F3 Now you will notice that all the occurrences are selected and highlighted Now hit Delete or Backspace Type different text, for my example I am typing "-prod" You can see that the text is now replaced with new value P.S.
