-NAME
-----
-stg-cp - stgdesc:cp[]
-
-SYNOPSIS
---------
-[verse]
-'stg' cp [OPTIONS] <file|dir> <newname>
-'stg' cp [OPTIONS] <files|dirs...> <dir>
-
-DESCRIPTION
------------
-
-Make git-controlled copies of git-controlled files. The copies are
-added to the Git index, so you can add them to a patch with
-stglink:refresh[].
-
-In the first form, copy a single file or a single directory, with a
-new name. The parent directory of <newname> must already exist;
-<newname> itself must not already exist, or the command will be
-interpreted as one of the second form.
-
-In the second form, copy one or several files and/or directories, into
-an existing directory.
-
-Directories are copied recursively. Only the git-controlled files
-under the named directories are copied and added to the index. Any
-file not known to Git will not be copied.
-
-CAVEATS
--------
-
-This command does not allow yet to overwrite an existing file (whether
-it could be recovered from Git or not). Further more, when copying a
-directory, the second form does not allow to proceed if a directory by
-that name already exists inside the target, even when no file inside
-that directory would be overwritten.
-
-FUTURE OPTIONS
---------------
-
-No options are supported yet. The following options may be
-implemented in the future.
-
---all::
- Also copy files not known to Git when copying a directory.
-
---force::
- Force overwriting of target files, even if overwritten files
- have non-committed changes or are not known to Git.
-
---dry-run::
- Show which files would be added, and which would be modified
- if --force would be added.
-
-StGIT
------
-Part of the StGIT suite - see gitlink:stg[1].
stg files
The 'stg refresh' command automatically notes changes to files that
-already exist in the working directory, but you have to tell StGIT
-explicitly if you add, remove, or rename files.
-To record the addition or deletion of files in your new patch:
+already exist in the working directory (it also notices if you remove
+them), but you have to tell StGIT explicitly if you add or rename a
+file:
- stg add [<file>*]
- stg rm [<file>*]
+ git add new-file
-To record the renaming of a file in your new patch, issue both of these
-commands:
+to add a file, and
+
+ mv old-file new-file
+ git add new-file
+
+or simply
+
+ git mv old-file new-file
- stg rm <oldfilename>
- stg add <newfilename>
+to move a file.
