Thank for your help. I want to get my code running.
Sorry to be blunt, but you first need to learn the basics of shell scripting, only then you can expect to get something - anything - running.

That's what i figured.

This will not only not work, it is also superfluous. If you use a pipeline you connect processes: process1 | process2 means: start process1 and whatever comes out of its stdout output channel (the part usually printed on screen) put into process2s stdin (normally connected to the keyboard). Since variable=value is not a process, there will be no output and hence nothing to feed your pipe.
I have told you already that capitalisation matters and that keywords are not "WHILE", but "while". What do you expect the shell to do if you write gibberish (^=unknown commands/keywords)?
My suggestion is to get some introductory book on shell programming and start reading it. You cannot expect to guess your way to some working code without knowing (obviously) neither UNIX nor shell and while we are willing to answer your questions we will not write complete scripts for you. Anything less than that, i suppose, would not suffice to get working code, though.
The 3rd line in your script:
sets the variable fpath to the string . and places it in the environment of the command it will then try to execute:
which will fail with one of two errors producing a diagnostic message similar to:
or:
Since you didn't show us anything like that in the output of the script that you ran, you didn't show us the script that you ran.
If, instead of:
your script had contained the command:
(with no space between the period and the slash and assuming that your current working directory when you ran your script was not /), that would be likely to lead to the results you showed us. If instead of either of the above, your script had contained the command:
(with neither the period nor the space), your script might do what you want. All of this is based on the assumption that the file you want to process is named /sas/scripts/OPTUMize/output/disk_utilization/disk_2016.10.25.txt and that there is no file named $PWD/sas/scripts/OPTUMize/output/disk_utilization/disk_2016.10.25.txt (where $PWD expands to your current working directory).

Is the column command available at all on your system?
As it is, i suppose there isn't:

no column in /usr/bin /etc /usr/sbin /usr/ucb /usr/bin/X11 /sbin /usr/local/bin /usr/local/sbin ~/bin
As an aside, i suggest you write ksh (instead of bash) scripts when it comes to AIX system maintenance, because the systems default shell is ksh. I have seen nothing in your scripts so far which would require bash.
