What about getting all the arguments after e.g. the third?
Write a test script and see:
Code:
$ cat args
#!/usr/bin/env bash
echo ${#}
echo All: "$@"
echo 3 to 5: ${@:3:3}
echo 2 to $#: ${@:2}
$ bash args a b c d e f g
7
All: a b c d e f g
3 to 5: c d e
2 to 7: b c d e f g
$ bash args a b c d e f g h i j
10
All: a b c d e f g h i j
3 to 5: c d e
2 to 10: b c d e f g h i j
