runcom

Runcom is a term used in Unix-like operating systems to refer to the system's initialization files, which are executed by the shell when a user logs in. These files are typically named ".profile", ".bashrc", ".bash_profile", or ".zshrc", depending on the shell being used. The runcom files are located in the user's home directory and are used to set up the user's environment, including environment variables, aliases, and functions.

The ".profile" file is executed for login shells, while the ".bashrc" file is executed for non-login interactive shells. The ".bash_profile" file is a variant of ".profile" that is specific to the Bash shell, and the ".zshrc" file is specific to the Zsh shell. These files can be edited using a text editor to customize the user's environment.

Runcom files are an essential part of the Unix-like operating system's initialization process, as they allow users to customize their environment to suit their needs. They are also used by system administrators to set up the environment for all users on a system.
