Question

Suppose you have the following script:

#!/usr/bin/ksh

for element in $@
    do
            echo $element
done

And you execute the script using:

./myscript.ksh "my element"

The expected output should be:

my element

but the whitespace is treated as a separator for each argument, obtaining:

my
element

How should I escape the whitespace?

Thanks

Answer 1

You must either quote the $@, or use nothing:

for element in "$@"

or

for element

will both work.
