method to force backgrounding a process without &

[punchykool]

can I force a script to run in the background without having my users place an ampersand at the end of the command line? nohup?

Say the script is:
line1
line2
...
lineN
You can change it like this:
(
line1
line2
...
lineN
) &

ping 192.168.0.9

shping.sh &

let the users call a script, which calls the script.

Thanks, PHV!
It works in bourne, but not in my lengthy csh script, which yields this error on my Sun OS 5.6 machine:

Too many ('s

Is there an alternative for csh?

I am trying to avoid a wrapper, stefanwagner, but thanks nonetheless

Perhaps replacing the outer pair ( ) by { }

no go.
csh still complains about the lone braces (just like it did with the parens) even if not alone on a line of code.
I also tried brackets with the same poor result. darn csh shell :-|

I suppose a wrapper will do unless someone else has a handy tip. Thanks very much all!

Try putting the following at start of your script.
Well it is a sort of wrapper. It is just that the script is its own wrapper.

if ( $#argv > 0 && $argv[1] == "--in-background") then
    shift
else
    $0 --in-background $* &
    exit
endif
