Sending attachments using email through shell script
Hi all,

I have written a shell script which sends emails with attachments to our clients. All our attachments are simple flat files (.txt format).

The script is working fine and sending the attachments to the mail-ids except that, when i am sending the attachments to non-outlook users (Like yahoo, gmail etc), i am seeing a junk character at the end of each line and the next line of file is appended to the previous line. In short all the data in the file is coming in one long line.

Here also there is a small twist. In gmail, there will be 2 options 2 download the file, View and Download. I am getting this problem only when i am downloading to the file to my local folder and viewing it.

Also when i am opening the same attachments in outlook, i can see that the data is appearing line by line as we entered it.

Kindly advise me, why this problem is occuring only when i am sending the mail to yahoo and gmail accounts. I am pasting the relavent code from my script.

glinvalidateframebuffer

GLINVALIDATEFRAMEBUF(3G)					   OpenGL Manual					  GLINVALIDATEFRAMEBUF(3G)

NAME

       glInvalidateFramebuffer - invalidate the content some or all of a framebuffer object's attachments

C SPECIFICATION

       void glInvalidateFramebuffer(GLenum target, GLsizei numAttachments, const GLenum * attachments);

PARAMETERS

       target
	   The target to which the framebuffer is attached.  target must be GL_FRAMEBUFFER, GL_DRAW_FRAMEBUFFER, or GL_READ_FRAMEBUFFER.

       numAttachments
	   The number of entries in the attachments array.

       attachments
	   The address of an array identifying the attachments to be invalidated.

DESCRIPTION

       glInvalidateFramebuffer invalidates the content of a specified set of attachments of a framebuffer. The framebuffer whose content to
       invalidate is indicated by setting target to the target to which it is bound.  target may be GL_FRAMEBUFFER, GL_READ_FRAMEBUFFER or
       GL_DRAW_FRAMEBUFFER.  GL_FRAMEBUFFER is treated as if it were GL_DRAW_FRAMEBUFFER.

       The set of attachments whose content to invalidate are specified in an array whose address is given by attachments and which contains
       numAttachments elements. The elements of attachments must be GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENTGL_DEPTH_STENCIL_ATTACHMENT, or
       GL_COLOR_ATTACHMENTi, where i is between zero and the value of GL_MAX_FRAMEBUFFER_ATTACHMENTS minus one. Furthermore, if the default
       framebuffer is bound to target, then attachments may contain GL_FRONT_LEFT, GL_FRONT_RIGHT, GL_BACK_LEFT, GL_BACK_RIGHT, GL_AUXi, GL_ACCUM,
       GL_COLOR, GL_DEPTH, or GL_STENCIL, identifying that specific buffer.  GL_COLOR, is treated as GL_BACK_LEFT for a double-buffered context
       and GL_FRONT_LEFT for a single-buffered context. After glInvalidateFramebuffer is executed, the contents of the specified attachments
       become undefined.

ERRORS

       GL_INVALID_ENUM is generated if target is not one of the accepted framebuffer target tokens.

       GL_INVALID_ENUM is generated if any element of attachments is not one of the accepted framebuffer attachment tokens.

       GL_INVALID_OPERATION is generated if element of attachments is GL_COLOR_ATTACHMENTi where i is greater than or equal to the value of
       GL_MAX_COLOR_ATTACHMENTS.

ASSOCIATED GETS

       glGet() with argument GL_MAX_COLOR_ATTACHMENTS
