Find everything that DOES NOT MATCH a specific string

[jwankhalaf-cx]

Hello everyone

I am working in .NET codebase and I want to find all namespaces that do not star with namespace ProjectX.. Is this possible with ripgrep?

For example, say I have a 100 C# code files, and most have their namespace declaration as:

namespace ProjectX.

But a few had:

namespace SomethingElse.

I want to ripgrep to list those that do not have the namespace namespace ProjectX.

How do I go about achieving that?

There may be a more efficient way, but something like this might work:

rg '^namespace[[:space:]]+' . | rg -v 'ProjectX'

Hah, beat me to it! Nice.

I would probably do something like rg '^namespace ' | rg -v ProjectX and see how that works.
