Is there a command in Git to see (either dumped to stdout, or in $PAGER or $EDITOR) a particular version of a particular file?

 

Yes, you can use the git show command to view a particular version of a file in Git. This command will display the content of the file as it existed at the specified commit. You can specify the commit and the file path as arguments. Here's how to use it with an example:

bash

git show <commit>:<file_path>

• <commit>: The commit hash or reference where you want to view the file's content.
• <file_path>: The path to the file you want to view.

Here's an example:

Suppose you have a Git repository, and you want to view the contents of a file named "example.txt" as it existed in a specific commit, let's say, commit abcdef123. You can use the following command:

bash

git show abcdef123:example.txt

Git will display the content of "example.txt" from the specified commit. If the file doesn't exist in the given commit, Git will indicate that the file is not found.

You can also use different commit references such as branch names, tags, or other commit expressions instead of commit hashes to view the file content at various points in your project's history.
