NAME¶

fw_printenv - Tool for printing the environment for the bootloader U-Boot

SYNOPSIS¶

fw_printenv [ name ... ]

DESCRIPTION¶

fw_printenv is a simple tool for printing the environment for the bootloader U-Boot. All environment variables matching the names given as arguments are shown. If fw_printenv is called without any arguments the entire environment is printed. This version of fw_printenv stems from libubootenv and does not hold a built-in default environment. Instead, the default environment is read from a file.
