.SH "NAME"
git-new-branch \- Create and switch to a new branch with correct tracking information\&.
.SH "SYNOPSIS"
.sp
.nf
\fIgit new\-branch\fR <branch_name>
\fIgit new\-branch\fR \-\-upstream_current <branch_name>
\fIgit new\-branch\fR \-\-upstream <REF> <branch_name>
\fIgit new\-branch\fR \-\-lkgr <branch_name>
\fIgit new\-branch\fR \-\-inject_current <branch_name>
.fi
.sp
.SH "DESCRIPTION"
.sp
Creates a new branch\&. By default the new branch will track the configured upstream for the repo (defaults to \fIorigin/main\fR)\&. If one of the other options is specified, it will track that other ref instead\&.
.sp
Conceptually, each branch in your repo represents one \fIChange List (CL)\fR\&. If you have many independent CLs (i\&.e\&. the changes in one do not interact with/depend on the changes in another), then you should create them as new branches tracking the default upstream (i\&.e\&. \fBgit new\-branch <branch_name>\fR)\&. If you have features which depend on each other, you should create stacked branches using \fBgit new\-branch \-\-upstream_current <branch_name>\fR\&.
.SH "OPTIONS"
.PP
\-\-upstream_current
.RS 4
Set the tracking (upstream) branch to the currently\-checked\-out branch\&.
.RE
.PP
\-\-upstream <REF>
.RS 4
Set the tracking (upstream) branch to <REF>\&. <REF> may be a local branch, remote branch, or a tag\&.
.RE
.PP
\-\-lkgr
.RS 4
Alias for
\fB\-\-upstream lkgr\fR\&.
.RE
.PP
\-\-inject_current
.RS 4
Set the tracking (upstream) branch of the newly\-created branch to the tracking (upstream) branch of the currently\-checked\-out branch and set the tracking (upstream) branch of the currently\-checked\-out branch to the newly\-created branch\&.

The name for the new branch\&.
.RE
.SH "CONFIGURATION VARIABLES"
.SS "depot\-tools\&.upstream"
.sp
This configures the default \fIupstream\fR for all new branches\&. If it is unset, it defaults to \fIorigin\fR\*(Aqs default branch or \fIorigin/main\fR if that can\(cqt be found\&. This is considered to be the \fIroot\fR branch\&.
