There is no reason either should happen. The variable length is limited only by available memory.

On the other side such trick could probably work as well: "for var in $(cat file); do .... done"
The is not the way to read a file. It sets var to each word in the file, not each line.

or better - use "read".... you might need to play with the FS/IFS settings.
There is no need to play with IFS to read a file line by line.

hobbit-statusreport.cgi
HOBBIT-STATUSREPORT.CGI(1) General Commands Manual HOBBIT-STATUSREPORT.CGI(1)
NAME
hobbit-statusreport.cgi - CGI program to report a status for a group of servers
SYNOPSIS
hobbit-statusreport.cgi --column=COLUMNNAME [options]
DESCRIPTION
hobbit-statusreport.cgi is a CGI tool to generate a simple HTML report showing the current status of a single column for a group of Xymon
hosts.
E.g. You can use this report to get an overview of all of the SSL certificates that are about to expire.
The generated webpage is a simple HTML table, suitable for copying into other documents or e-mail.
hobbit-statusreport.cgi runs as a CGI program, invoked by your webserver. It is normally run via a wrapper shell-script in the CGI direc-
tory for Xymon.
EXAMPLES
The Xymon installation includes two web report scripts using this CGI tool: The hobbit-certreport.sh script generates a list of SSL server
certificates that are yellow or red (i.e. they will expire soon); and the hobbit-nongreen.sh script generates a report of all statuses that
are currently non-green. These can be accessed from a web browser through a URL referencing the script in the Xymon CGI directory (e.g.
"/xymon-cgi/xymon-nongreen.sh").
OPTIONS
--column=COLUMNNAME
Report the status of the COLUMNNAME column.
--all Report the status for all hosts known to Xymon. By default, this tool reports only on the hosts found on the current page from where
the CGI was invoked (by looking at the "pagepath" cookie).
--filter=CRITERIA
Only report on statuses that match the CRITERIA setting. See the bb(1) man-page - in the "hobbitdboard" command description - for
details about specifying filters.
--heading=HTML
Defines the webpage heading - i.e. the "title" tag in the generated HTML code.
--show-column
Include the column name in the display.
--show-colors
Show the status color on the generated webpage. The default is to not show the status color.
--no-colors
Do not include text showing the current color of each status in the report. This is the default.
--show-summary
Show only a summary of the important lines in the status message. By default, the entire status message appears in the generated
HTML code. This option causes the first non-blank line of the status message to be shown, and also any lines beginning with "&COLOR"
which is used by many status messages to point out lines of interest (non-green lines only, though).
--show-message
Show the entire message on the webpage. This is the default.
--link Include HTML links to the host "info" page, and the status page.
--embedded
Only generate the HTML table, not a full webpage. This can be used to embed the status report into an external webpage.
--env=FILENAME
Load the environment from FILENAME before executing the CGI.
--area=NAME
Load environment variables for a specific area. NB: if used, this option must appear before any --env=FILENAME option.
