Chapter 8
Scripting and Reporting

This chapter provides details about using p4 commands in scripts and for reporting purposes. For a full description of any particular command, consult the Perforce Command Reference, or issue the p4 help command.

Common flags used in scripting and reporting

The following command-line flags enable you to specify settings on the command line and in scripts. For full details, refer to the description of global options in the Perforce Command Reference.

Flag
Description

-c client_workspace

Specifies the client workspace name.

-G

Causes all output (and batch input for form commands with -i) to be formatted as marshaled Python dictionary objects.

-p server:port

Specifies the host and port number of the Perforce server.

-P password

Specifies the user password if any. If you prefer your script to log in before running commands (instead of specifying the password every time a command is issued), use the p4 login command. For example:

echo 'mypassword' | p4 login

-s

Prepends a descriptive field (for example, text:, info:, error:, exit:) to each line of output produced by a Perforce command.

-u user

Specifies the Perforce user name.

-x argfile

Reads arguments, one per line, from the specified file. If argfile is a single hyphen (-), then standard input is read.

Scripting with Perforce forms

If your scripts issue p4 commands that require the user to fill in a form, such as the p4 client and p4 submit commands, use the the -o flag to write the form to standard output and the -i flag to read the edited form from standard input.

For example, to create a job using a script on UNIX:

  1. Issue the p4 job -o > temp1 command to write a blank job specification into a text file.

  2. Make the necessary changes to the job. For example:

  3. Issue the p4 job -i < temp2 command to save the job.

To accomplish the preceding without a temporary file, issue the following command:

p4 job -o | sed 's/<enter description here>/Crash when exiting./' | p4 job -i The commands that display forms are:

File reporting

The following sections describe commands that provide information about file status and location. The following table lists a few basic and highly-useful reporting commands.

To display this information
Use this command

File status, including file type, latest revision number, and other information

p4 files

File revisions from most recent to earliest

p4 filelog

Currently opened files

p4 opened

Preview of p4 sync results

p4 sync -n

Currently synced files

p4 have

The contents of specified files

p4 print

The mapping of files' depot locations to the corresponding workspace locations.

p4 where

A list of files and full details about the files

p4 fstat

Displaying file status

To display information about single revisions of files, issue the p4 files command. This command displays the locations of the files in the depot, the actions (add, edit, delete, and so on) performed on those files at the specified revisions, the changelists in which the specified file revisions were submitted, and the files' types. The following example shows typical output of the p4 files command:

The p4 files command requires one or more filespec arguments. Regardless of whether you use local, client, or depot syntax to specify the filespec arguments, the p4 file command displays results using depot syntax. If you omit the revision number, information for the head revision is displayed. The output of p4 files includes deleted revisions.

The following table lists some common uses of the p4 files command.

To display the status of
Use this command

All files in the depot, regardless of your client workspace view

For depots containing numerous files, you can maximize performance by avoiding commands that refer to the entire depot (//depot/...) when not required. For best performance, specify only the directories and files of interest.

p4 files //depot/...

The files currently synced to the specified client workspace

p4 files @clientname

The files mapped by your client workspace view

p4 files //clientname/...

Specified files in the current working directory

p4 files filespec

A specified file revision

p4 files filespec#rev

Specified files at the time a changelist was submitted, regardless of whether the files were submitted in the changelist

p4 files filespec@changenum

Files tagged with a specified label

p4 files filespec@labelname

Displaying file revision history

To display the revision history of a file, issue the p4 filelog filespec command. The following example shows how p4 filelog displays revision history.

p4 filelog //depot/dev/main/jam/jam.c

//depot/dev/main/jam/jam.c
... #35 change 627 edit on 2001/11/13 by [email protected] (text) 'Handle platform variants better'
... #34 change 598 edit on 2001/10/24 by [email protected] (text) 'Reverse previous attempt at fix'
... ... branch into //depot/release/jam/2.2/src/jam.c#1
... #33 change 581 edit on 2001/10/03 by [email protected] (text) 'Version strings & release notes'

To display the entire description of each changelist, specify the -l flag.

Listing open files

To list the files that are currently opened in a client workspace, issue the p4 opened filespec command. The following line is an example of the output displayed by the p4 opened command:

The following table lists some common uses of the p4 opened command.

To list
Use this command

Opened files in the current workspace

p4 opened

Opened files in all client workspaces

p4 opened -a

Files in a numbered pending changelist

p4 opened -c changelist

Files in the default changelist

p4 opened -c default

Whether a specific file is opened by you

p4 opened filespec

Whether a specific file is opened by anyone

p4 opened -a filespec

Displaying file locations

To display information about the locations of files, use the p4 where, p4 have, and p4 sync -n commands:

You can use these commands with or without filespec arguments.

The following table lists some useful location reporting commands.

To display
Use this command

The revision number of a file that you synced to your workspace

p4 have filespec

How a particular file in the depot maps to your workspace

p4 where //depot/filespec

Displaying file contents

To display the contents of a file in the depot, issue the p4 print filespec command. This command prints the contents of the file to standard output or to a specified output file, with a one-line banner that describes the file. To suppress the banner, specify the -q flag. By default, the head revision is displayed, but you can specify a file revision.

To display the contents of files
Use this command

At the head revision

p4 print filespec

Without the banner

p4 print -q filespec

At a specified changelist number

p4 print filespec@changenum

Displaying annotations (details about changes to file contents)

To find out which file revisions or changelists affected lines in a text file, issue the p4 annotate command.

By default, p4 annotate displays the file line by line, with each line preceded by a revision number indicating the revision that made the change. To display changelist numbers instead of revision numbers, specify the -c flag.

Monitoring changes to files

To track changes to files as they occur, you can use the Perforce change review daemon, which enables Perforce users to specify files and directories of interest and receive email when a changelist that affects the specified files is submitted. For details about administering the review daemon, refer to the Perforce System Administrator's Guide and to the description of the p4 review command in the Perforce Command Reference.

The following table lists commands that display information about the status of files, changelists, and users. These commands are often used in review daemons.

To list
Use this command

The users who review specified files

p4 reviews filespec

The users who review files in a specified changelist

p4 reviews -c changenum

A specified user's email address

p4 users username

Changelist reporting

The p4 changes command lists changelists that meet search criteria, and the p4 describe command lists the files and jobs associated with a specified changelist. These commands are described below.

Listing changelists

To list changelists, issue the p4 changes command. By default, p4 changes displays one line for every changelist known to the system. The following table lists command-line flags that you can use to filter the list.
