Hi,
As I mentioned previously, there are shortcomings in man bash. Here, I
just point another example. And I hope my suggestion will be
addressed.
As a reasonable search strategy to search for how to set $@ is to
search for '$@' in man bash. The literal word '$@' appears at the
following locations.
...performed, with the exception of "$@" as explained below under Special...
...expands to a separate word. That is, "$@" is equivalent to "$1"...
...When there are no positional parameters, "$@" and $@ expand to...
...of "$@" and "${name[@]}" as explained above (see PARAMETERS)...
Search for 'set --' returns nothing. And search for '--' is prohibited
as there are too many of them. If the manual discusses how to 'set
$@', then it is at least hard to find. My suggestion is to add a new
paragraph to the existing discussion of $@, so that by searching $@,
readers can easily see how set $@.
@ Expands to the positional parameters, starting from one. When
the expansion occurs within double quotes, each parameter
expands to a separate word. That is, "$@" is equivalent to "$1"
"$2" ... If the double-quoted expansion occurs within a word,
the expansion of the first parameter is joined with the begin-
ning part of the original word, and the expansion of the last
parameter is joined with the last part of the original word.
When there are no positional parameters, "$@" and $@ expand to
nothing (i.e., they are removed).
As others pointed out LDP/abs is a more readable document, the
following link is a much better document on helping me to find how to
set "$@".
