The following script:
echo $#
shift 3
echo $#
echo shifting two more:
shift 2
echo $#
Produces the following output for sh (ash) and bash:
$ sh shiftest a b c d
4
1
shifting two more:
shift: can't shift that many
1
$ bash shiftest a b c d
4
1
shifting two more:
1
The only difference is the error message generated by ash. The final
result is the same, the last shift did not change the argument count.
I don't think this is a bug in either of shells, unless you want to
count not printing an error as the bug. It is a bug in the original
script, however.
