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.
