Please become accustomed to provide decent context info of your problem.
It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two including your own attempts at a solution, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

envsubst
ENVSUBST(1) GNU ENVSUBST(1)
NAME
envsubst - substitutes environment variables in shell format strings
SYNOPSIS
envsubst [OPTION] [SHELL-FORMAT]
DESCRIPTION
Substitutes the values of environment variables.
Operation mode:
-v, --variables
output the variables occurring in SHELL-FORMAT
Informative output:
-h, --help
display this help and exit
-V, --version
output version information and exit
In normal operation mode, standard input is copied to standard output, with references to environment variables of the form $VARIABLE or
${VARIABLE} being replaced with the corresponding values. If a SHELL-FORMAT is given, only those environment variables that are referenced
in SHELL-FORMAT are substituted; otherwise all environment variables references occurring in standard input are substituted.
When --variables is used, standard input is ignored, and the output consists of the environment variables that are referenced in SHELL-FOR-
MAT, one per line.
