_______________________________________________________
Details:
man page of grep shows
--label=LABEL
Displays input actually coming from standard input as input com-
ing from file LABEL. This is especially useful for tools like
zgrep, e.g. gzip -cd foo.gz |grep --label=foo something
but this example command does not print the label "foo";
"-H" is necessary.
When we use grep from standard input only, "-H" is always
necessary.
In addition, "zgrep" is shown, but it is not used
in this sample.
