I have made a program that reads a text file and checks for palindromic words and then outputs them. They each appear on a new line with a count of the number of occurences beside each of the words.
Requirements for being classed as palindrome are that the word must have at least 3 letters and at least 2 of them must be different. For example, eee would not be a palindrome but eye would be.
I am having a problem in that my program is picking up some of the words such as eee and iii. I have added the grep command highlighted below to try and fix this but I keep coming up against these errors. I cannot seem to get it to work.

cracklib-unpacker
cracklib-format(8) Debian GNU/Linux manual cracklib-format(8)NAME
cracklib-format, cracklib-packer, cracklib-unpacker - cracklib dictionary utilities
SYNOPSIS
cracklib-format file ...
cracklib-packer cracklib_dictpath
cracklib-unpacker cracklib_dictpath
DESCRIPTION
cracklib-format takes a list of text files each containing a list of words, one per line, It lowercases all words, removes control charac-
ters, and sorts the lists. It outputs the cleaned up list to standard output. The text files may be optionally compressed with gzip(1).
If you supply massive amounts of text to cracklib-format you must have enough free space available for use by the sort(1) command. If you
do not have 20Mb free in /var/tmp (or whatever temporary area your sort(1) command uses), have a look at the /usr/sbin/cracklib-format pro-
gram which is a sh(1) program. You can usually tweak the sort(1) command to use any large area of disk you desire, by use of the -T
option. cracklib-format has a hook for this.
cracklib-packer reads from standard input a list of sorted and cleaned words and creates a database in the directory and prefix given by
the command line argument cracklib_dictpath. Three files are created with the suffixes of .hwm, .pwd, and .pwi. These three files are in
the format that the FascistCheck(3) subroutine, cracklib-unpacker(8), and cracklib-check(8), utilities understand. The number of words
read and written are printed on stdout(3).
cracklib-unpacker reads from the database in the directory and prefix given by the command line argument cracklib_dictpath and outputs on
standard output the list of words that make up the database.
The database is in a binary format generated by the utilities cracklib-format(8) and cracklib-packer(8). On a Debian system the database
is located in the directory /var/cache/cracklib/cracklib_dict and is generated daily with the program /etc/cron.daily/cracklib. The loca-
tion is also defined in the header file crack.h using the constant CRACKLIB_DICTPATH though none of the subroutines in the cracklib
libraries have this location hardcoded into their implementations.
FILES
/var/cache/cracklib/cracklib_dict.[hwm|pwd|pwi]
cracklib dictionary database files used by utilities.
/etc/cron.daily/cracklib
cracklib daily cron program to rebuild the cracklib dictionary database.
/etc/cracklib/cracklib.conf
cracklib configuration file used by the cracklib daily cron program to rebuild the cracklib dictionary database.
/usr/include/crack.h
cracklib header file defining the subroutine FascistCheck(3) and the constant CRACKLIB_DICTPATH used to compile in the location of
the cracklib dictionary database for these utilities.
/usr/sbin/cracklib-format
cracklib shell script to create initial list of words for dictionary database.
