# p4 add

Open files in a client workspace for addition to the depot.

## Syntax

    p4 [g-opts] add [-c changelist] [-d -f -I -n] [-t filetype] file ...

Syntax and naming conventions

## Description

p4 add opens files within the client workspace for addition to the depot. The specified files are linked to a changelist. The command can add files to a new, empty depot or to a depot that already contains files. The files are added to the depot when the changelist is committed with `p4 submit`. The added files must either not already exist in the depot, or be marked as deleted at the head revision.

`p4 add *` is equivalent to `p4 reconcile -a *`.

To open a file with `p4 add`, the file must exist in your client view, but does not need to exist in your workspace at the time of `p4 add`. The file must exist in your workspace when you run `p4 submit`. If not, the submission fails.

`p4 add` does not create or overwrite files in your workspace. If a file does not exist, you must create it yourself.

By default, the specified files are opened in the default changelist. To open the files in a specified changelist, use the `-c` option.

To move files from the default changelist to a numbered changelist, use the `p4 change` command.

By default, `p4 add` skips over files mentioned in any applicable `P4IGNORE` files. To override this behavior, use the `-I` option to ignore the contents of any `P4IGNORE` files.

When adding files, the command first examines the typemap table (`p4 typemap`) to see if the system administrator has defined a file type for the files being added. If a match is found, the file’s type is set as defined in the typemap table. If a match is not found, the command examines the first bytes of the file based on the filesys.binaryscan configurable (by default, 65536 bytes) to determine whether it is `text` or `binary`, and the files are stored in the depot accordingly. By default, text file revisions are stored in reverse delta format. Newly-added text files larger than the limit imposed by the filetype.maxtextsize configurable (by default, 10 MB) are assigned filetype `text+C` and stored in full. Files compressed in the `.zip` format (including `.jar` files) are also automatically detected and assigned the type `ubinary`. Other binary revisions are stored in full, with compression.

The `-t filetype` option explicitly specifies a file type, overriding both the typemap table and the default file type detection mechanism.

To add files containing the characters `@`, `#`, `*`, and `%`, use the `-f` option. This option forces literal interpretation of characters otherwise used by P4 Server as wildcards.

If you open a file for edit or move/add, and another user subsequently deletes the file you opened, the operation will fail with an error when you submit the changelist. To ensure that you create the desired target file, specify the `-d` option ("downgrade"). More specifically:

- You open a file for edit, then another user submits a changelist that deletes or moves the file. When you submit your edits, P4 Server returns an error and the file remains open for edit. To restore the file (including any changes you have made) to the depot location from which you checked it out, open the file for add and specify the `-d` option, then submit the file.
- You open a file for move/add and another user submits a changelist that deletes the source file. When you submit the move, P4 Server returns an error and the file remains open for add/move. To create the desired target file, issue the `p4 add -d` command, specifying the target file, and submit the file.

## Options

Option | Description
--- | ---
`-c changelist` | Opens the files for `add` within the specified changelist. If this option is not used, the files are linked to the default changelist.
`-d` | Downgrade file open status to simple add.
`-f` | Use the `-f` option to force inclusion of wildcards in filenames. See File specifications for details. Filenames that contain the special characters '@', '#', '%', or '*' are reformatted to encode the characters using ASCII hexadecimal representation. After the files are added, refer to them using the reformatted file name instead of the local file system name.
`-I` | Do not perform any ignore checking; ignore any settings specified by `P4IGNORE`.
`-n` | Preview which files would be opened for add, without actually changing any files or metadata.
`-t filetype` | Adds the file as the specified filetype, overriding any settings in the typemap table. See Base file types and modifiers as well as the lbr.autocompress configurable.
`g-opts` | See Global options.

## Usage notes

Can File Arguments Use Revision Specifier? | Can File Arguments Use Revision Range? | Minimal Access Level Required
--- | --- | ---
No | No | `open`

- The local operating system expands the * wildcard (see Wildcards) in file specifications provided to `p4 add`.

- Do not use ASCII expansions of special characters with `p4 add -f`. To add the file `status@june.txt`, use:

  `p4 add -f status@june.txt`

  If you manually expand the `@` sign and attempt to add the file `status%40june.txt`, P4 Server interprets the `%` sign literally, expands it to the hex code `%25`, resulting in the filename `status%2540june.txt`.

- See also Default ignored paths in the p4 ignores topic.

## Examples

`p4 add -t binary file.pdf` | Assigns a specific file type to a new file, overriding any settings in the typemap table.
p4 add -t text+D fileA.txt | Stores the specified file in RCS format, which is uncompressed and, for this file, overrides the default setting of the lbr.autocompress configurable.
`p4 add -c 13 *` | Opens all the files within the user’s current directory for `add`, and links these files to changelist `13`.
`p4 add README ~/src/*.c` | Opens the `README` file in the user’s current working directory for `add`. Opens all `*.c` files in the user’s `~/src` directory for `add`. These files are linked to the default changelist
`p4 add -f *.c` | Opens a file named `*.c` for `add`. To refer to this file in views, or with other commands, you must subsequently use the hex expansion `%2A` in place of the asterisk. To learn more, see Limitations on characters in filenames and entities.
