Csplit command problem in Linux
Hi All,

I have recently join the forum and this is my first post....hoping to get a suggestion to a problem that I am facing.

I have a script that works well on ksh unix on AIX server. The below mentioned code checks number of records in an input file starting with 99 and splits it accordingly and creates new files. i.e. if there are two records starting with 99 then two new files are created.

Format of data in the input file:
10ABC 20150624
99ABC 20150624
10DEF 20150624
99DEF 20150624

Code:
SPLTNME=${FILENAME}_${$}
#--getting no. of footer records in the file
NUM=`grep "^99" ${FILENAME} | wc -l`
REPEAT=`expr $NUM - 2`
csplit -n4 -s -k -f ${SPLTNME} ${FILENAME} /^99/1 {$REPEAT} > /dev/null 2>&1

In case if there is a single 99 record in the input file, the value of REPEAT is set to -1. In AIX the code works and it looks like

Code:
csplit -n4 -s -k -f ${SPLTNME} ${FILENAME} /^99/1 {-1} > /dev/null 2>&1

Now, I am trying to run the same script in Linux, but the above "csplit" code is not working.

The "-1" value of repeat is not recognised in linux. I guess it only recognises postive integers where pattern repeatation is mentioned.

To fix this, I tried hardcoding positive value like 1...it worked but created two files instead and out of the two, one is 0 byte file. It seems that the above csplit code line needs modification in order to run it in Linux.

Could you please suggest any alternative to make this part of the code work in linux.

Details of Linux version is: Red Hat Linux release 6.6 (Santiago)
shell: ksh

Thanks,
Sanjay

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

       glIsEnabled with argument GL_CULL_FACE
       glGet with argument GL_CULL_FACE_MODE

SEE ALSO

       glEnable, glFrontFace
