core-validate-commit:tldr:f484e

This command is a combination of two commands in Git, using some shell syntax. Let's break it down:

1. git rev-list ${commit_hash}..HEAD:

   • git rev-list is a command that lists commit objects in reverse chronological order. It can take various options to specify a range of commits.
   • ${commit_hash} is a placeholder for a specific commit hash. It should be replaced with an actual commit hash you want to start from.
   • ..HEAD specifies the range from the specified commit until the latest commit in the current branch (HEAD). Therefore, this part of the command lists all the commits starting from ${commit_hash} up to the latest commit in the current branch.

2. | xargs core-validate-commit:

   • | is a pipe operator that allows the output of the previous command to be used as input for the next command.
   • xargs is a command that takes input from standard input (in this case, the list of commit hashes) and executes another command with it.
   • core-validate-commit is a command that is being executed by xargs. It could be a custom script or a command provided by the Git repository you are working with.

So, in summary, this command lists all the commits starting from ${commit_hash} until the latest commit in the current branch, and then runs a command core-validate-commit on each commit using the xargs command. The purpose of the core-validate-commit command is specific to the Git repository you are working with.
