This KornShell code is throwing the following error:

if [ ${fooVariable} = "" ]; then
    fooVariable="fooString"
fi

echo "${fooVariable}"

Error:

@:/tmp #./test.ksh
./test.ksh[3]: test: 0403-004 Specify a parameter with this command.

Solution:

Put double quotes around variable.

test.ksh

#! /usr/bin/ksh

if [ "${fooVariable}" = "" ]; then
    fooVariable="fooString"
fi

echo "${fooVariable}"

Output:

@:/tmp #./test.ksh
fooString
