grep

Basic Usage

1. Search for a Pattern in the Working Directory

   To search for a pattern in the working directory, use the following command:

   git grep "pattern"

   This will search for the specified pattern in all files tracked by Git in the current working directory.

2. Search for a Pattern in a Specific Branch

   To search for a pattern in a specific branch, use the -b option followed by the branch name:

   git grep "pattern" branch_name

3. Search for a Pattern in a Specific Commit

   To search for a pattern in a specific commit, use the commit hash:

   git grep "pattern" commit_hash

4. Search for a Pattern in a Specific Directory

   To limit the search to a specific directory, specify the directory path:

   git grep "pattern" -- path/to/directory

5. Search for a Pattern with Line Numbers

   To include line numbers in the search results, use the -n option:

   git grep -n "pattern"

Examples

1. Search for the Word "TODO" in the Entire Repository

   git grep "TODO"

2. Search for the Word "FIXME" in the main Branch

   git grep "FIXME" main

3. Search for the Word "bug" in a Specific Commit
