| − | Usage: 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.
