git-fame:tldr:86407

The given command "git fame --excl "${regular_expression}"" executes a command-line tool called "git fame" with an additional option "--excl" followed by a regular expression "${regular_expression}".

Here's how the different parts of the command work:

• git: This is a version control system that allows you to track changes in files and collaborate with others. The "git" command is used to interact with a Git repository.

• fame: "git fame" is a command-line tool extension for Git that provides a way to analyze and display the contribution statistics of authors in a Git repository. It shows the fame/top contributors based on various metrics such as the number of commits, file changes, lines of code, etc. The command "git fame" must be installed as an extension before running this command.

• --excl: This is an option provided by the "git fame" tool. It allows you to exclude certain files or paths from being considered in the contribution statistics calculation. By using this option, you can provide a specific regular expression to define the files or paths that should be excluded.

• "${regular_expression}": This is a placeholder that represents a regular expression. Regular expressions are powerful patterns used to match and manipulate text. In the context of the "git fame" command, you can provide a regular expression to define specific files or paths that should be excluded. For example, if you want to exclude all files in a "tests" directory, you can use a regular expression like "/tests/". The regular expression is enclosed within double quotes to ensure proper handling of spaces or special characters within it.

By running the "git fame --excl "${regular_expression}"" command, you will get the contribution statistics from "git fame" considering the regular expression provided in "${regular_expression}" to exclude specific files or paths from the analysis.
