My apologies again. I have been up working on a number of different emergencies this week until about 3am each night. This PDF issue is just one problem I am having at the moment and my attention is divided. I'm not trying to rile anyone up. Thank you again for looking at this.
I will reopen the original thread and merge this post. into it.
OBTW, I am not "riled" or upset or angry in any way. I am like a "admin robot"... I just insure this site is healthy, running fast and smooth, protect the site from harm, and insure our mission, rules and guidelines are followed.
SOAP BOX COMMENT: Sidebar (not specific to your post):
Sometimes I ask a question or ask for input, to insure that questions are clear, not only for me, but for future generations who visit the site and have similar questions. This site is not a "put a nickel in and get an answer out site", as some would like it to be. Our mission is to teach people to solve their own problems, not to do other's work for them, like the old saying (paraphrasing) which I am sure you have heard before:
"Give a person a fish and you feed them for a day. Teach that same person to fish, and you feed them for a lifetime."
In the age of the Internet and social media, people have become too dependant on others to do their problem solving (and thinking) for them. When I created this site decades ago, long before FB, reddit, stack*, medium, and more; our goals were always to have a very high "signal to noise" ratio and to never become a "put a nickel in and get an answer site", to encourage people to describe and solve their own problems with our help.
I will continue to encourage all users in that direction, even if we are the last site on the Internet to be this way.

I am trying to use the csplit file on a file that contains records that have more than 2048 characters on a line. The resultant split file seems to ignore the rest of the line and I lose the data.
Is there any way that csplit can handle record lengths greater than 2048?

pdftotext
pdftotext(1) General Commands Manual pdftotext(1) NAME
pdftotext - Portable Document Format (PDF) to text converter (version 3.00) SYNOPSIS
pdftotext [options] [PDF-file [text-file]] DESCRIPTION
Pdftotext converts Portable Document Format (PDF) files to plain text. Pdftotext reads the PDF file, PDF-file, and writes a text file, text-file. If text-file is not specified, pdftotext converts file.pdf to file.txt. If text-file is '-', the text is sent to stdout. OPTIONS
-f number Specifies the first page to convert. -l number Specifies the last page to convert. -r number Specifies the resolution, in DPI. The default is 72 DPI. -x number Specifies the x-coordinate of the crop area top left corner -y number Specifies the y-coordinate of the crop area top left corner -W number Specifies the width of crop area in pixels (default is 0) -H number Specifies the height of crop area in pixels (default is 0) -layout Maintain (as best as possible) the original physical layout of the text. The default is to 'undo' physical layout (columns, hyphen- ation, etc.) and output the text in reading order. -raw Keep the text in content stream order. This is a hack which often "undoes" column formatting, etc. Use of raw mode is no longer recommended. -htmlmeta Generate a simple HTML file, including the meta information. This simply wraps the text in <pre> and </pre> and prepends the meta headers. -bbox Generate an XHTML file containing bounding box information for each word in the file. -enc encoding-name Sets the encoding to use for text output. This defaults to "UTF-8". -listenc Lits the available encodings -eol unix | dos | mac Sets the end-of-line convention to use for text output. -nopgbrk Don't insert page breaks (form feed characters) between pages. -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) BUGS
Some PDF files contain fonts whose encodings have been mangled beyond recognition. There is no way (short of OCR) to extract text from these files. EXIT CODES
The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error. AUTHOR
