Hejhej,

I am trying to rewrite a /bash/ script to be POSIX compilant, so it will
work with /dash/.
In this script there is a function call lile this:

getmounts >$TMPSRC #getmounts is the function obviously

in /dash/ it never actually calls that function, and just drops out of the
script.
Now I am not really sure, but I think in /bash/ it translates to
redirecting the return value of the
funtion into the variable TMPSCR, how would I achieve this while staying
POSIX compilant?

Thanks in advance,
Thomas

The above happens to be POSIX and *not* bash.

It redirects the standard output of getmounts to the file whose
name is contained in the $TMPSRC variable.

In bash (when bash is not called as "sh"), you need the quotes
around $TMPSRC:

getmounts > "$TMPSRC"

which also is standard POSIX syntax of course.

What makes you think it doesn't work in dash?

Duh, actually you are right, it does work.
Then I have to keep searching for the actual error :(

Thank you very much though,
Thomas
