In this article, we will see a very useful command to search for a particular text inside your project.
Many times when working on code, you want to find out where in the repository a particular text is used, either to replace it with other text or for debugging purpose.
If you try to use a global search in your favorite IDE like Visual Studio Code or Sublime Text, you will get the text you are searching in hundreds or thousands of files like package.json
, package-lock.json
, and other un-necessary files.
Instead, you can use git grep
command to quickly search within files. So let’s dive into it.
Suppose, you want to find the files in which a particular statement like require("express")
or require('express')
is used, just using a global search for express in VS Code will give many results, instead we can run the following command from a terminal in your repository.
git grep -n $'require([\'"]express[\'"]'
The above command will list out the filename, line number along with the matching text from that file
This will produce the output as shown below:
Suppose you want to find in which files, a particular property like http_mode
from app object is used.
In short, if you want to find the occurrence of .http_mode
you can execute the following command:
git grep $'\.http_mode'
This will produce the output as shown below:
If you want to find the text NavLink
only in a particular directory instead of all the directories, you can execute the following command:
grep -rn src/routes -e NavLink
This will produce the output as shown below:
Conclusion
As you have seen, using simple git and grep combination you can quickly find the required text instead of looking through thousands of files in your IDE search.
