p4config

p4config is a configuration file used by the Perforce Helix Core version control system. It allows users to specify settings and preferences for their Perforce client or server interactions without needing to set environment variables or pass command-line arguments for every command. The p4config file typically resides in the user's home directory or within a specific project directory.

This file enables customization of various Perforce client behaviors. For instance, it can define the default Perforce server (P4PORT), the user's username (P4USER), and the workspace name (P4CLIENT). It can also include settings related to security, such as specifying the location of a P4TICKET file for authentication, or network-related configurations like timeouts.

The p4config file uses a simple key-value pair format. Each line in the file represents a configuration setting, with the configuration name followed by an equals sign and then its value. For example, P4PORT=perforce.example.com:1666 would set the default server to perforce.example.com on port 1666.

By centralizing these settings, p4config simplifies the Perforce user experience, especially for users who interact with multiple Perforce servers or work on various projects with different configurations. It promotes consistency and reduces the likelihood of errors arising from incorrect or missing command-line arguments. Perforce commands automatically read and apply settings from the p4config file if it is present in the expected locations.
