# git-rlog.sh - Show git log decorated with SVN revisions
|
|
#
|
|
# Usage: git-rlog.sh [<options>] [<revision range>] [[--] <path>…]
|
|
#
|
|
# Example: $ git-rlog.sh origin/svn/trunk
|
|
#
|
|
# Accepts the same options as git-log (see: git-log(1) for details).
|
|
# Revision range are documented in man page: gitrevisions(7).
|
|
#
|
|
# You can either use this script directly or add it to your git aliases in
|
|
# ~/.gitconfig or .git/config:
|
|
#
|
|
# [alias]
|
|
# rlog = !$(git rev-parse --show-toplevel)/scripts/git-rlog.sh
|
|
#
|
|
# With alias configured, you will be able to invoke it as other git commands:
|
|
#
|
|
# $ git rlog
|
|
#
|
|
# You can read more about aliases in the manual: git-config(1)
|
