Data Alternative for wc -l

Hi techies ..

This is my first posting hr ..

Am facing a serious performance problem in counting the number of lines in the file. The input files i get will be in some 10 to 15 Gb of size or even sometimes more ..and I will load it to db

I have used wc -l to confirm whether the loader has loaded entire data ...the couting operaion alone consumes more than 45 to 50 mins ...could someone suggest me any other way to get the count of lines in files ..Smilie

pls note I cant use sed due to the coding standards followed here ..so pls excuse ..

Any other swifting workaround would be really helpfull ..and appreciatedSmilie

NAME
glFrontFace - define front- and back-facing polygons C SPECIFICATION
void glFrontFace( GLenum mode ) PARAMETERS
mode Specifies the orientation of front-facing polygons. GL_CW and GL_CCW are accepted. The initial value is GL_CCW. DESCRIPTION
In a scene composed entirely of opaque closed surfaces, back-facing polygons are never visible. Eliminating these invisible polygons has the obvious benefit of speeding up the rendering of the image. To enable and disable elimination of back-facing polygons, call glEnable and glDisable with argument GL_CULL_FACE. The projection of a polygon to window coordinates is said to have clockwise winding if an imaginary object following the path from its first vertex, its second vertex, and so on, to its last vertex, and finally back to its first vertex, moves in a clockwise direction about the interior of the polygon. The polygon's winding is said to be counterclockwise if the imaginary object following the same path moves in a counterclockwise direction about the interior of the polygon. glFrontFace specifies whether polygons with clockwise winding in window coordinates, or counterclockwise winding in window coordinates, are taken to be front-facing. Passing GL_CCW to mode selects counterclock- wise polygons as front-facing; GL_CW selects clockwise polygons as front-facing. By default, counterclockwise polygons are taken to be front-facing. ERRORS
GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_OPERATION is generated if glFrontFace is executed between the execution of glBegin and the corresponding execution of glEnd. ASSOCIATED GETS
