WC -l does not count all the lines in a file? HELP
I have a file that I need to merge with another like file. Normally I remove the trailer reocrd and merge the file and update the trailer record of the second file. I did a WC -l on the first file before I removed the trailer record, and again afterwards. The count came back the same. I opened the file with textpad and found that the file with the trailer record had 1 more line than what WC -l was bringing back. I need help from the experts on this.

Image::ExifTool::AFCP(3)				User Contributed Perl Documentation				  Image::ExifTool::AFCP(3)

NAME

       Image::ExifTool::AFCP - Read/write AFCP trailer

SYNOPSIS

       This module is used by Image::ExifTool

DESCRIPTION

       This module contains definitions required by Image::ExifTool to extract information from the AFCP trailer.  Although the AFCP specification
       is compatible with various file formats, ExifTool currently only processes AFCP in JPEG images.

NOTES

       AFCP is a specification which allows meta information (including IPTC) to be appended to the end of a file.

       It is a poorly designed protocol because (like TIFF) it uses absolute offsets to specify data locations.  This is a huge blunder because it
       makes the AFCP information dependent on the file length, so it is easily invalidated by image editing software which doesn't recognize the
       AFCP trailer to fix up these offsets when the file length changes.  ExifTool will attempt to fix these invalid offsets if possible.

       Scanning for AFCP information may be time consuming, especially when reading from a sequential device, since the information is at the end
       of the file.  In these instances, the ExifTool FastScan option may be used to disable scanning for AFCP information.
