Description




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  stan-
     dard 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 refer-
     ences occurring in standard input are substituted.

     When --variables is used, standard input is ignored, and the
     output consists of the environment variables that are refer-
     enced in SHELL-FORMAT, one per line.
