envsubst - substitutes environment variables in shell format strings
envsubst [OPTION] [SHELL-FORMAT]
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-
FORMAT, one per line.
