This particular approach is a destructive action and if you're not using version control and you write an error into your script, you could incorrectly and permanently alter files in a negative way. I highly recommend tracking these files with git so you can protect against mistakes. Let's consider an instance where you want to remove a particular string "Hello World" followed by two newlines i.
Where you put this script so it can be run is entirely up to you and the way in which you like to work. In general, there are three solid ways in which you can run a ruby script:. Open an IRB instance, paste the command and then run it. In general, if it's a one-off task you're only going to run a single time, the IRB console is usually the way to go. That way you don't have to store any code. You write it, run it, and then forget about it.
If it's something you're going to run again, or if you may use something similar to it in the future, it may be worth storing as a standalone script or an executable. But I can't figure out a solution.
Can you help me? Calling the function the way I am doing it is important for me. Perhaps the most efficient way to evaluate all the patterns for every line is to build a single regexp from all the search patterns and use the hash replacement form of String gsub. How are we doing?

For more details on regex , refer to the search with regex documentation. Click the icon to filter your search. For example, you can filter the search to omit comments or search only in comments instead.
Select one of the displayed options such as Module or Directory to limit your search. Moreover, you can select the Scope option that offers you a list of predefined scopes for your search.
For example, you can limit your search to the test files in your project. You can also create your own custom scope, click the Browse icon to open the Scopes dialog. Use the File Mask option to narrow your search to a specific file type. You can select the existing file type from the list, add a new file type, or add an additional file mask syntax to search for file types with certain patterns. In the Find in Files dialog, select the File Mask checkbox and from the list of file types, select the one you need.
If you don't find the file type you need in the list, enter your file type in the File Mask field. In the top field, enter your search string.
