You don't use the same shell for your two different test. When you run your script with the
Code:
$ sh -x unix_12.sh

you use sh, when you run your script with the
Code:
$ unix_12.sh

you use csh as specified by the shebang
Code:
#!/bin/csh

Replace the shebang by
Code:
#!/bin/sh

or better by the shell which is linked to /bin/sh
