git-reflog:tldr:60672
The command "git reflog -n ${5}" is used to display the abbreviated commit IDs and action details of the most recent git operations or commands that have been executed in your repository.
Here's a breakdown of the command:
-
"git reflog" is the base command that is used to access the reference logs in Git. Reference logs are a chronological record of all the operations performed in the repository, such as commits, branch creations, merges, etc.
-
"-n" is an option that specifies the number of entries from the reference log that you want to display. In this case, "${5}" is a placeholder for the numerical value that will be provided by the user. It indicates that you want to display the most recent ${5} entries from the reflog.
When you execute this command, Git will retrieve the specified number of recent records from the reference log and display them in the console. Each entry will include an abbreviated commit ID (usually the first 7 characters of the full commit ID) and information about the action performed, such as the branch affected, the operation type, etc. This can be useful for troubleshooting, exploring past commits, or recovering lost changes.
