Hiya,
$ bash -c 'printf "%s\n" "${@:2}"' x 1 2 "3 4" 5

$ bash -c 'IFS=a; printf "%s\n" "${@:2}"' 0 1 2 "3 4" 5
2 3 4 5
I don't understand why $IFS would have any influence here. The
behavior differs from ksh.
It seems that you need to have " " in IFS or IFS being unset for
it to work as I would expect.
Also, this:
$ bash -c 'printf "%s\n" "${@:1}"' x 1 2 "3 4" 5
1

3 4
5
$ bash -c 'a=("$@"); printf "%s\n" "[EMAIL PROTECTED]:1}"' x 1 2 "3 4" 5
2
3 4
5
I find is quite confusing.
The behavior is the same in ksh, but in ksh ${@:0:1} expands to
$0 which makes it more understandable ($0 has its meaning in
functions as well in ksh which makes it somehow consistent).
In bash, ${@:0:1} and ${@:1:1} expand to the same thing ($1). Is
all that documented (I couldn't find it via a quick scan of the
man page)?
Best regards,
Stephane
