p4 client

Synopsis

Syntax

Description

Although there is always a one-to-one mapping between a client workspace file and a depot file, these files do not need to be stored at the same relative locations, nor must they have the same names. The client view, which is specified in the p4 client form's View: field, specifies how files in the client workspace are mapped to the depot, and vice-versa.

When called without a clientname argument, p4 client operates on the client workspace specified by the P4CLIENT environment variable or one of its equivalents. If called with a clientname argument on a locked client, the client specification is read-only.

When p4 client completes, the new or altered client workspace specification is stored within the Perforce database; the files in the client workspace are not touched. The new client view doesn't take effect until the next p4 sync.

The command p4 workspace is an alias for p4 client.

Form Fields

Field Name	Type	Description
Client:	Read-only	The client workspace name, as specified in the P4CLIENT environment variable or its equivalents.
Owner:	Writable	The Perforce user name of the user who owns the client workspace. The default is the user who created the client workspace.
Update:	Read-only	The date the client workspace specification was last modified.
Access:	Read-only	The date and time that any part of the client workspace specification was last accessed by any Perforce command.
Host:	Writable, optional	The name of the host machine on which this client workspace resides. If included, operations on this client workspace can be run only from this host. The hostname must be provided exactly as it appears in the output of p4 info when run from that host. This field is meant to prevent accidental misuse of client workspaces on the wrong machine. It doesn't provide security, since the actual value of the host name can be overridden with the -H flag to any p4 command, or with the P4HOST environment variable. For a similar mechanism that does provide security, use the IP address restriction feature of p4 protect.
Description:	Writable, optional	A textual description of the client workspace. The default text is Created by owner.
Root:	Writable, mandatory	The directory (on the local host) relative to which all the files in the View: are specified. The default is the current working directory.
AltRoots:	Writable, optional	Up to two optional alternate client workspace roots. Perforce client programs use the first of the main and alternate roots to match the client program's current working directory. This enables users to use the same Perforce client specification on multiple platforms with different directory naming conventions. If you are using a Windows directory in any of your client roots, you must specify the Windows directory as your main client root and specify your other client root directories in the AltRoots: field. For example, an engineer building products on multiple platforms might specify a main client root of C:\Projects\Build for Windows builds, and an alternate root of /staff/userid/projects/build for any work on UNIX builds.
Options:	Writable, mandatory	A set of seven switches that control particular client options. See the Usage Notes, below, for a listing of these options.
LineEnd:	Writable, mandatory	A set of four switches that control carriage-return/linefeed (CR/LF) conversion. See the Usage Notes, below, for a listing of these options.
View:	Writable, multi-line	Specifies the mappings between files in the depot and files in the client workspace. See Views for more information.

Options

-t clientname	Copy client workspace clientname's view and client options into the View: and Options: field of this client workspace. (i.e, use clientname's View: as a template)
-f	Allows the last modification date, which is normally read-only, to be set. Can also be used by Perforce superusers to delete or modify clients that they don't own.
-d [-f] clientname	Delete the specified client workspace, if the client is owned by the invoking user or it is unlocked. (The -f flag allows Perforce superusers to delete locked client workspaces that they don't own.)
-i	Read the client description from standard input.
-o	Write the client specification to standard output.
g-opts	See the Global Options section.

• Use quotation marks to enclose depot-side or client side mappings of file or directory names that contain spaces.

• Spaces in client workspace names are translated to underscores. For example, typing the command p4 client "my client" creates a client workspace called my_client.

• The Options: field contains six values, separated by spaces. Each of the six options have two possible settings; the following table provides the option values and their meanings:

  Option	Choice	Default
  [no]allwrite	If set, unopened files on the client are left writable.	noallwrite
  [no]clobber	If set, a p4 sync overwrites ("clobbers") writable-but-unopened files in the client that have the same name as the newly-synced files	noclobber
  [no]compress	If set, the data stream between the client and the server is compressed. (Both client and server must be version 99.1 or higher, or this setting is ignored.)	nocompress
  [no]crlf	Note: 2000.2 or earlier only! On Windows, if crlf is set, CR/LF translation is performed automatically when copying files between the depot and the client workspace.	crlf
  [un]locked	Grant or deny other users permission to edit the client specification (To make a locked client specification truly effective, you should also set a the client's owner's password with p4 passwd.) If locked, only the owner is able to use, edit, or delete the client spec. Perforce administrators can override the lock by using the -f (force) flag with p4 client.	unlocked
  [no]modtime	For files without the +m (modtime) file type modifier: For Perforce clients at the 99.2 level or earlier, if modtime is set, the modification date (on the local filesystem) of a newly synced file is the date and time at the server when the file was submitted to the depot. For Perforce clients at the 2000.1 level or higher, if modtime is set, the modification date (on the local filesystem) of a newly synced file is the datestamp on the file when the file was last modified. If nomodtime is set, the modification date is the date and time of sync, regardless of Perforce client version. For files with the +m (modtime) file type modifier: For Perforce clients at the 99.2 level or earlier, the +m modifier is ignored, and the behavior of modtime and nomodtime is as documented above. For Perforce clients at the 2000.1 level or higher, the modification date (on the local filesystem) of a newly synced file is the datestamp on the file when the file was submitted to the depot, regardless of the setting of modtime or nomodtime on the client.	nomodtime (i.e. date and time of sync) for most files. Ignored for files with the +m file type modifier.
  [no]rmdir	If set, p4 sync deletes empty directories in a client if all files in the directory have been removed.	normdir

• By default, any user can edit any workspace specification with p4 client -c clientname. To prevent this from happening, set the locked option and use p4 passwd to create a password for the client workspace owner.

• The compress option speeds up client/server communications over slow links by reducing the amount of data that has to be transmitted. Over fast links, the compression process itself may consume more time than is saved in transmission. In general, compress should be set for line speeds under T1, and should be left unset otherwise.

• The LineEnd: field controls the line-ending character(s) used for text files in the client workspace.

  Note	The LineEnd: option is new to Perforce 2001.1. It renders the previous convention of specifying crlf or nocrlf in the Options: field obsolete. The behavior of the mutually-contradictory combination of LineEnd: win and Options: crlf is undefined.

The LineEnd: field accepts one of five values:

Option	Meaning
local	Use mode native to the client (default).
unix	UNIX-style line endings: LF only.
mac	Macintosh-style: CR only.
win	Windows-style: CR, LF.
share	Shared mode: Line endings are LF with any CR/LF pairs translated to LF-only style before storage or syncing with the depot. When you sync your client workspace, line endings will be LF. If you edit the file on a Windows machine, and your editor inserts CRs before each LF, the extra CRs will not appear in the archive file. The most common use of the share option is for users of Windows workstations who have UNIX home directories mounted as network drives; if they sync files from UNIX, but edit the files on the Windows machine, the share option eliminates any problems caused by Windows-based editors' insertion of extra carriage return characters at line endings.

• By default, if a directory in the client workspace is empty, (for instance, because all files in the depot mapped to that directory have been deleted since the last sync), a p4 sync operation will still leave the directory intact. If you use the rmdir option, however, p4 sync deletes the empty directories in the client workspace.

If the rmdir option is active, a p4 sync operation may sometimes remove your current working directory. If this happens, just change to an existing directory before continuing on with your work.

• Files with the modtime (+m) type are primarily intended for use by developers who need to preserve original timestamps on files. The use of +m in a file type overrides the client's modtime or nomodtime setting. For a more complete discussion of the +m modifier, see the File Types section.

• If you are using multiple or alternate client roots (the AltRoots: field), you can always tell which client root is in effect by looking at the Client root: reported by p4 info.

• To specify a Perforce client on Windows that spans multiple drives, use a Root: of null, and specify the drive letters in the client workspace view. For instance, the following client spec with a null client root maps //depot/main/... to an area of the C: drive, and other releases to the D: drive:

  Client: eds_win Owner:  edk Description:          Ed's Windows Workspace Root:   null Options:        nomodtime noclobber View:         //depot/main/...     "//eds_win/C:/Current Release/..."         //depot/rel1.0/...   //eds_win/D:/old/rel1.0/...         //depot/rel2.0/...   //eds_win/D:/old/rel2.0/...

Use uppercase drive letters when specifying workspaces across multiple drives.
