In Linux you can do this to put comma separated data on its own line like this.
sed 's/ */&\n/g' /tmp/ports
sed 's/ */\n/g' /tmp/ports
How do you do this in AIX? It is not working. Is there another way to do this? Something like this.
1, 2, 3, 4

GLDRAWTRANSFORMFEEDB(3G) OpenGL Manual GLDRAWTRANSFORMFEEDB(3G) NAME
glDrawTransformFeedback - render primitives using a count derived from a transform feedback object C SPECIFICATION
void glDrawTransformFeedback(GLenum mode, GLuint id); PARAMETERS
mode Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES, GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY, GL_TRIANGLES_ADJACENCY, and GL_PATCHES are accepted. id Specifies the name of a transform feedback object from which to retrieve a primitive count. DESCRIPTION
glDrawTransformFeedback draws primitives of a type specified by mode using a count retrieved from the transform feedback specified by id. Calling glDrawTransformFeedback is equivalent to calling glDrawArrays() with mode as specified, first set to zero, and count set to the number of vertices captured on vertex stream zero the last time transform feedback was active on the transform feedback object named by id. ERRORS
GL_INVALID_ENUM is generated if mode is not an accepted value. GL_INVALID_VALUE is generated if id is not the name of a transform feedback object. GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is currently mapped. GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object. GL_INVALID_OPERATION is generated if mode is GL_PATCHES and no tessellation control shader is active. GL_INVALID_OPERATION is generated if glEndTransformFeedback() has never been called while the transform feedback object named by id was bound. SEE ALSO
