grep line that is start with 'int'
I like to use the 'grep' to grep all line that starts with 'int' whether there is space, tabs in front of 'int'
more filename | grep int
"|" is called the pipe sign
grep '^[ ]*int' filename
LOL I think I spoke too early.

What I try to do is look for all line that int variable declaration line? So I need to find all integer variables declaration line.
so I have to be able to grep all these lines
int i ;
int a;
\t\t int b;
so I have to be able to grep all these lines
int i ;
int a;
\t\t int b;
do as I said earlier
more filename | grep int
more filename | grep int
there are two characters in the [ ], one is a space, ad the other is a tab

but I do not want to pick up a line that contain 'int' in another word.
What I try to is to grep all the line with the word 'int' at the beginning of the line.
