Help with bulk deletion

[Bryantdl7]

So I am trying to find a way to delete all strings that contain "new" in the script structure below

Code: [Select]

"STEAM_0:0"
{
"name" "mX"
"deny"
{
}
"allow"
{
}
"group" "new"
}However, as you can tell I am working with steam ID's so it is not as simple as imputting it into ms word and doing a replace action, I want to delete everything I put inside that code box above. I was wondering if anyone knows of a program that can delete the entire string if it contains a certain variable, such as "group"   "new"
I am cleaning out my users.txt file as it has over 41 thousand lines, and i want to quickly delete everyone from the database while saving my staff from being deleted.

If I confused you guys I can try and explain it better

Use notepad++'s replace feature. It accepts regex expressions and you can just replace it with nothing.

Code: [Select]

"STEAM_0:(0|1):\d+"\s\n{\n\s matches a steamid followed by the first brace and some spaces and newlines

Code: [Select]

"deny"\s\n\s{\n\s\}\n\s matches "deny" followed by some spaces, new lines, and braces

Code: [Select]

"allow"\s\n\s{\n\s\}\n\s matches "allow" followed by some spaces, new lines, and braces

Code: [Select]

"name"\s".+\n\s matches "name" and someones name, followed by some spaces and new lines

Code: [Select]

"group"\s"new"\n\}\n matches "group" and "new", followed by some spaces and new lines and the closing brace and then another newline

all put together:

Code: [Select]

"STEAM_0:(0|1):\d+"\s\n{\n\s"deny"\s\n\s{\n\s\}\n\s"allow"\s\n\s{\n\s\}\n\s"name"\s".+\n\s"group"\s".+"\n\}\n
Of course because of the genius of users.txt, the deny, allow, and name fields can be in any order. Hip hurray! (I'm sure there must be a good reason for this, and I'm curious what that reason is. It's just also pretty irritating.)

Just go ahead and re-order those three elements (total of six possible combinations) and you should be able to get them all.

Thank you so much! It worked perfectly! users.txt 407kb down to 41 kb!

I really need to learn more about regex haha, looks powerful.

Yea I've never used it before, but it seemed like it would work for this. I just used an online regex tester that also had a regex cheatsheet. It was much easier than I expected.

RegEx is awesome and used in so many different coding/scripting languages for string manipulation it's incredible.
I too never learned even 1% of what it can do.
RoastChicken, though I'm sure we could all find one or two using Google, you should share your link that helped you.

The site I used was https://regex101.com/, but as you said there are tons of regex testers out there. I like  this site in particular because it explains what each character in your command does, so you can find mistakes more easily.
