p4 add


Open file(s) in a client workspace for addition to the depot.


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


p4 add opens files within the client workspace for addition to the depot. The specified file(s) are linked to a changelist; the files are not actually added to the depot until the changelist is committed with p4 submit. The added files must either not already exist in the depot, or exist in the depot but be marked as deleted at the head revision.

The commands p4 add * or p4 add ... are synonymous to p4 reconcile -a * — that is, all files in the workspace that do not exist in the depot will be opened for add. Using the -a option does not affect the behavior of p4 add -d .

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, however, exist in your workspace when you run p4 submit, or the submission will fail. 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, Perforce first examines the typemap table (p4 typemap) to see if the system administrator has defined a file type for the file(s) 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, Perforce 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 Perforce's 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 Perforce as wildcards.

If you open a file for edit or move/add, and another 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, Perforce 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, Perforce 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.


-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.


Downgrade file open status to simple add.


Use the -f option to force inclusion of wildcards in filenames. See “File Specifications” for details.


Do not perform any ignore checking; ignore any settings specified by P4IGNORE.


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 “File Types” for a list of Perforce file types.


See “Global Options”.

  • Wildcards in file specifications provided to p4 add are expanded by the local operating system, not by the Perforce service. For instance, the ... wildcard cannot be used with p4 add.

  • In Perforce, there is no difference between adding files to an empty depot and adding files to a depot that already contains other files. You can populate new, empty depots by adding files from a client workspace with p4 add.

  • Do not use ASCII expansions of special characters with p4 add -f. To add the file [email protected], use:

    p4 add -f [email protected]

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


p4 add -t binary file.pdf

Assigns a specific file type to a new file, overriding any settings in the typemap table.

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 all *.c files in the user's ~/src directory for add; also opens the README file in the user's current working 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 Perforce commands, you must subsequently use the hex expansion %2A in place of the asterisk.
