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
