Thanks for bringing this to my attention. Indeed, there appears to be
field splitting not done correctly, but at least it’s not m̲y̲ fault ☺
tg@frozenfish:~ $ pdksh -c 'x="X 1"; echo shift ${x#X}'
shift 1
(That on Debian etch.)
Looking further¹:
tg@blau:~ $ x="X 1"; dumpargs shift ${x#X}
args(3) 0:/usr/local/bin/dumpargs 1:shift 2: 3:1
tg@blau:~ $ x="X 1 2"; dumpargs shift ${x#X}
args(4) 0:/usr/local/bin/dumpargs 1:shift 2: 3:1 4:2
So, apparently, the leading space creates an empty field.
Meh. On the other hand…
tg@blau:~ $ mksh /usr/src/contrib/code/Snippets/ifs.sh
# tests 6856 passed 6856 failed 0
The script – now http://www.research.att.com/~astopen/public/ifs.sh
as everything ~gsf/ seems to have been moved – hasn’t changed either,
which means you found something not covered by any existing tests.
I’ll look at this.
