24 In normal operation mode, standard input is copied to standard output,
25 with references to environment variables of the form $VARIABLE or ${VARIABLE}
26 being replaced with the corresponding values. If a SHELL-FORMAT is given,
27 only those environment variables that are referenced in SHELL-FORMAT are
28 substituted; otherwise all environment variables references occurring in
29 standard input are substituted.
31 When \fB\-\-variables\fR is used, standard input is ignored, and the output consists
32 of the environment variables that are referenced in SHELL-FORMAT, one per line.
