I have a directory with many text files.
Out of these files, I am interested in a word "abcdefghi". I need to list all possible cases of this word such as
- abcdefghi
- abcdefghI
- abcDefghi
- ABCDEFGHI
and all other possible combinations.
It is possible with grep or egrep?
I know, I can write a shell script with combos of grep and inverse grep, unique and achieve the outputs, but I am looking for portable solution.

Have you tried the man page?

Tried, failed. Maybe too dumb to make sense of man pages.

What you want is called case-insensitive match. Use the-iswitch for that.

@JosephR. It will print while whole line, I just need the matched word. See Avinash's answer below.

With GNU grep, try this:
grep -io -- 'abcdefghi' *.txt
I assumed all the files you want to search for a particular text would be ended with .txt (and you don't want the hidden ones).
From man grep on a system where grep is GNU's implementation (as is typical on Linux-based systems).
-o, --only-matching show only the part of a line matching PATTERN
-i, --ignore-case ignore case distinctions
