[SOLVED] perl matching??

ashok.g · 02-02-2010, 06:02 AM

Hi,
I am using perl.

Code:

if( $b =~ m/$inf/ )
{
	print "$b$inf";
}

Actually $b and $inf contains a string value seperated with tabs.
When I execute the above code this code is not executing. why???

By "not executing", do you mean just that nothing is output, or that you are getting an error message?

A match should be found if the contents of $inf can be interpreted as a regular expression that matches $b (meaning that it could be as simple as a substring of $b):

[rh@mypc ~]$ perl -e '$b = "one\ttwo\tthree"; $inf = "\ttwo"; if($b =~ m/$inf/) {print "$b$inf\n";}'
one two three two

Could you give an example of the strings contained by $b and $inf?

Actually the problem lies in getting the inf from files.
Please refer to post where I did some what different.
