UNIX for Dummies Questions & Answers

Hi,
Can any one please explain me the use of 'typeset' in shell scripting?
I donot under stand the use and advantages of using typeset.
In one of our script, it is written like

Code:

typeset VERBOSE NO_UPDATE
typeset LOAD_SYBASE_TABLES

I donot understand what actually these lines do.
As per my understanding to set variable, we can use set or export.

Can any one please explain elaborately?

Thanks,
Siba S Nayak

We use typeset to declare variables and/or give them attributes. If no names are given then display the values of variables. The -p option will display the attributes and values of each name. When -p is used, additional options are ignored. The -F option inhibits the display of function definitions; only the function name and attributes are printed. The -F option implies -f. The following options can be used to restrict output to variables with the specified attribute or to give variables attributes.

You can check man pages for details

Hi Amit,
Thanks a lot. How typeset is different from set or export, which also used to set the variables?
