Problem with global and local variables - Shell Programming and Scripting

qzv2jm · #1 (**permalink**) 03-03-2008

Guys, how can I define global variables in sorlaris...cause I lose the values outside the scope.

Rite now wat I do is,I redirect variable value to a file n then get it back outside the function...

....theres obviously a better way of doing this...I now this is a basic question....but please help.....

Are you talking about C?

Code:

int this_is_global=0;

void foo(void)
{
    this_is_global=7;
}

int main()
{
      printf("before: %d ", this_is_global);
      foo();
      printf(" after: %d\n", this_is_global);
}

Is it shell script? - the syntax depends on what shell you are using

Code:

echo $SHELL

will show you your shell. We need to know which shell you are using.

or better yet - to get the 'active' shell interpreter:

Code:

echo $0
