Find all palindromes of four characters or less
I got this far that is the code searches the bigtextfile for words with 4 characters or less then store those characters to a palindromes text file. The problem I am having is that I don't know how to find the palindromes. The 4 character words that are stored to palidromes text file must be a palindrome word. Any help is appreciated.

awk '{

for(i=1;i<=NF;i++)

{

if(length($i)<5)

{print $i}

}

}' bigTextFile.txt > palindromes.txt

Maybe you should ask your teacher.
