Newbie help - parsing through a file

Hello guys,

I am a newbie to all of this - I'd like some help with a file I have. It's a ~100mb CSV file with approximately 30 columns.

What I'd like to do is to search through the file and REMOVE any lines with a certain case insensitive string in any of the columns:

So my file looks like this:

Code:
1, Mike Smith, 12, Philly
2, John Smith, Right, New York
3, Tommy, $@, Atlanta
4, Nate New, $@, Atlanta

I'd like to search through this file, and remove any line with the word "new" in it, so my final file would look like this:

Code:
1, Mike Smith, 12, Philly
3, Tommy, $@, Atlanta

NAME
slags2.f - SYNOPSIS
Functions/Subroutines subroutine slags2 (UPPER, A1, A2, A3, B1, B2, B3, CSU, SNU, CSV, SNV, CSQ, SNQ) SLAGS2 Function/Subroutine Documentation subroutine slags2 (logicalUPPER, realA1, realA2, realA3, realB1, realB2, realB3, realCSU, realSNU, realCSV, realSNV, realCSQ, realSNQ) SLAGS2 Purpose: SLAGS2 computes 2-by-2 orthogonal matrices U, V and Q, such that if ( UPPER ) then U**T *A*Q = U**T *( A1 A2 )*Q = ( x 0 ) ( 0 A3 ) ( x x ) and V**T*B*Q = V**T *( B1 B2 )*Q = ( x 0 ) ( 0 B3 ) ( x x ) or if ( .NOT.UPPER ) then U**T *A*Q = U**T *( A1 0 )*Q = ( x x ) ( A2 A3 ) ( 0 x ) and V**T*B*Q = V**T*( B1 0 )*Q = ( x x ) ( B2 B3 ) ( 0 x ) The rows of the transformed A and B are parallel, where U = ( CSU SNU ), V = ( CSV SNV ), Q = ( CSQ SNQ ) ( -SNU CSU ) ( -SNV CSV ) ( -SNQ CSQ ) Z**T denotes the transpose of Z. Parameters: UPPER UPPER is LOGICAL = .TRUE.: the input matrices A and B are upper triangular. = .FALSE.: the input matrices A and B are lower triangular. A1 A1 is REAL A2 A2 is REAL A3 A3 is REAL On entry, A1, A2 and A3 are elements of the input 2-by-2 upper (lower) triangular matrix A. B1 B1 is REAL B2 B2 is REAL B3 B3 is REAL On entry, B1, B2 and B3 are elements of the input 2-by-2 upper (lower) triangular matrix B. CSU CSU is REAL SNU SNU is REAL The desired orthogonal matrix U. CSV CSV is REAL SNV SNV is REAL The desired orthogonal matrix V. CSQ CSQ is REAL SNQ SNQ is REAL The desired orthogonal matrix Q.
