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 ..
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 appreciated

glcullface
GLCULLFACE(3G) GLCULLFACE(3G) NAME
glCullFace - specify whether front- or back-facing facets can be culled C SPECIFICATION
void glCullFace( GLenum mode ) PARAMETERS
mode Specifies whether front- or back-facing facets are candidates for culling. Symbolic constants GL_FRONT, GL_BACK, and GL_FRONT_AND_BACK are accepted. The initial value is GL_BACK. DESCRIPTION
glCullFace specifies whether front- or back-facing facets are culled (as specified by mode) when facet culling is enabled. Facet culling is initially disabled. To enable and disable facet culling, call the glEnable and glDisable commands with the argument GL_CULL_FACE. Facets include triangles, quadrilaterals, polygons, and rectangles. glFrontFace specifies which of the clockwise and counterclockwise facets are front-facing and back-facing. See glFrontFace. NOTES
If mode is GL_FRONT_AND_BACK, no facets are drawn, but other primitives such as points and lines are drawn. ERRORS
GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_OPERATION is generated if glCullFace is executed between the execution of glBegin and the corresponding execution of glEnd. ASSOCIATED GETS
