Input parameters

UNIX AIX
1

friends


and I can validate whether to run the shell has input parameters m event date, I occasionally happen something like this does not work

if $ 1 is null then
echo has entered input parameters
else
echo "parameter ok"
fi
2

That will never work: bad syntax everywhere.
Try this

if (( $# )) ; then echo "number of parameters = $#" ; fi
