Top Forums UNIX for Dummies Questions & Answers grep sed Post 88600 by ericelysia on Monday 7th of November 2005 07:36:36 AM

I have made some modifications using some basic commands. I want to allow the user to change a record.

Code:
cat<<here

Please enter the record number of the particular record to change:

here

read number

record=`sed -n ${number}p phonebook`

name=`echo $record|cut -d: -f1`
echo $name

echo Do you want to change the name: "$name"
read answer
if[ "$answer" = "y" ]
then
echo "Please enter new name"
read newname
name=$newname
fi

I am now trying to use the sed command to remove the record (the number the user entered).

I also plan to add the new fields back into the file.

Code:
sed -d '${number}'

This is not right. Any suggestions?

Thanks,
Eric

glflushmappedbufferrange

GLFLUSHMAPPEDBUFFERR(3G)					  [FIXME: manual]					  GLFLUSHMAPPEDBUFFERR(3G)

NAME

       glFlushMappedBufferRange - indicate modifications to a range of a mapped buffer

C SPECIFICATION

       GLsync glFlushMappedBufferRange(GLenum target, GLintptr offset, GLsizeiptr length);

PARAMETERS

       target
	   Specifies the target of the flush operation.  target must be GL_ARRAY_BUFFER, GL_COPY_READ_BUFFER, GL_COPY_WRITE_BUFFER,
	   GL_ELEMENT_ARRAY_BUFFER, GL_PIXEL_PACK_BUFFER, GL_PIXEL_UNPACK_BUFFER, GL_TEXTURE_BUFFER, GL_TRANSFORM_FEEDBACK_BUFFER, or
	   GL_UNIFORM_BUFFER.

       offset
	   Specifies the start of the buffer subrange, in basic machine units.

       length
	   Specifies the length of the buffer subrange, in basic machine units.

DESCRIPTION

       glFlushMappedBufferRange indicates that modifications have been made to a range of a mapped buffer. The buffer must previously have been
       mapped with the GL_MAP_FLUSH_EXPLICIT flag.  offset and length indicate the modified subrange of the mapping, in basic units. The specified
       subrange to flush is relative to the start of the currently mapped range of the buffer.	glFlushMappedBufferRange may be called multiple
       times to indicate distinct subranges of the mapping which require flushing.

ERRORS

       GL_INVALID_VALUE is generated if offset or length is negative, or if offset + length exceeds the size of the mapping.

       GL_INVALID_OPERATION is generated if zero is bound to target.

       GL_INVALID_OPERATION is generated if the buffer bound to target is not mapped, or is mapped without the GL_MAP_FLUSH_EXPLICIT flag.

       glMapBufferRange(), glMapBuffer(), glUnmapBuffer()
