6.1.1

Automatic startup file

Immediately after starting, the UEFI shell checks for the startup.nsh file in the defined execution path.
If the file exists, the shell executes the commands specified in the file. Then, it waits for command input from the
console. This situation does not always require the startup.nsh file.
Remarks
The execution path is the directory path specified in the shell environment path variable. You can display and
change this directory path by using the set command.

UEFI shell command syntax

To access an environment variable value as an argument for a shell command, enclose the variable name in percent
signs (%), as shown below.

command.
The file name argument in shell commands uses the following characters as wildcards: *, ?, [, and ].
