Using the vim editor to create a script file in the context of environmental variables primarily serves the purpose of changing and exporting the SHELL environmental variable. The SHELL variable defines the path to the command interpreter that will be used when executing commands in a terminal session. By creating a script, you can modify this variable temporarily or set it to a specific shell that better meets your needs.

In creating such scripts, one typically writes commands to either set or export the SHELL variable, influencing how subsequent commands will behave in the terminal. This ability to customize the shell environment is essential for creating workflows that align with user preferences or system requirements.

The other choices do not directly align with the primary functionality of scripting and environmental variables. Setting user permissions pertains to filesystem security, creating a backup of the existing profile relates to data preservation, and installing new software packages involves package management rather than environmental configuration. Thus, the relevance of using vim in this context is firmly rooted in modifying and exporting the SHELL variable.
