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 corre-
sponding 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 envi-
ronment variables that are referenced in SHELL-FORMAT, one per line.
