You can have the interpretor check your syntax (Korn) by adding one of the following lines below the "magic number" in your script. Also note that the options can be enabled or disabled by using (+) or (-) signs.
set -x (Show commands and arguments during execution)
set -n (Read the commands but dont execute - syntax check)
NAME
set, unset, setenv, unsetenv, export - shell built-in func-
tions to determine the characteristics for environmental
variables of the current shell and its descendents
its for sh/ksh/csh shells.
it is checked for syntax only if you "set" the proper switches.
otherwise it is just sent as is and will error out if there is an error.

For example instead of /what_i_have_now/
I'd like to change just ONE field to the opposite with an exclamation point.
Like this: ! /what_i_have_now/
My question, where am I supposed to place... (1 Reply)
