|
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.
|
|
<P>
|
|
|
|
When <B>--variables</B> is used, standard input is ignored, and the output consists
|
|
of the environment variables that are referenced in SHELL-FORMAT, one per line.
