Package: posh
Version: 0.13.2
Severity: normal
If a posh script uses the nounset option (set -o nounset or set -u)
posh can not handle "$@" if no args are given ($# = 0)
To show the problem a test script t1 can be prepared:
bs@sid:~$ cat <<'END' >t1
> set -u
> f1() { echo "number of args $#"; }
> f1 "$@"
> END
bs@sid:~$ chmod 755 t1
In the following tests every shell will output as expected: number of args 2
bs@sid:~$ posh ./t1 "one two" three
number of args 2
bs@sid:~$ bash ./t1 "one two" three
number of args 2
bs@sid:~$ dash ./t1 "one two" three
number of args 2
bs@sid:~$ busybox sh ./t1 "one two" three
number of args 2
bs@sid:~$ mksh ./t1 "one two" three
number of args 2
In the following tests posh will output: ./t1:3: @: parameter not set
instead of the expected: number of args 0
bs@sid:~$ posh ./t1
./t1:3: @: parameter not set
bs@sid:~$ bash ./t1
number of args 0
bs@sid:~$ dash ./t1
number of args 0
bs@sid:~$ busybox sh ./t1
number of args 0
bs@sid:~$ mksh ./t1
number of args 0
