 ** find
+*** grep
+- grep TEXT-TO-FIND LOCATION
+
+- this will recursively go through all files in a directory looking for "TEXT"
+        #+begin_src bash
+        grep -R  TEXT .
+        #+end_src
+
+*** ripgrep
+**** Key Features of rg (ripgrep):
+- Faster than grep (built with Rust and optimized for performance).
+- Ignores files listed in .gitignore by default.
+- Supports recursive searches automatically.
+- Better default output formatting.
+- Supports regex matching like grep -E.
+- Multithreaded searching for better performance on modern CPUs.
+
+**** basic command structure
+- search recursively through all files for text
+  #+begin_src bash
+  rg "text"
+  #+end_src
+
+- case insensitive search
+  #+begin_src bash
+  rg -i "text"
+  #+end_src
+
+- show line numbers
+  #+begin_src bash
+  rg -n "text"
+  #+end_src
+
+- search files of the pattern shown
+
+  #+begin_src bash
+  rg "text" --glob "*.txt"
+  #+end_src
+
+- search through files that are classified under the type given
+  - pattern example
+        #+begin_src bash
+        rg "text" -t txt
+        #+end_src
+  - for example type 'txt' would search for
+    - txt
+    - md
+    - rst
+  - if you want to see the type list use
+  #+begin_src bash
+  rg --type-list
+  #+end_src
+
+- ask for a specified number of lines of context around search match
+        #+begin_src bash
+        rg "text" -C 3
+        #+end_src
+
+- dont ignore hidden files
+        #+begin_src bash
+        rg "text" -u
+        #+end_src
+
+- add stats to search
+        #+begin_src bash
+        rg "text" --stats
+        #+end_src
+
+*** other alternatives
