[SOLVED] return matching but not exact same strings

Issue

Is there any way to find a word that contains a given string but is not the exact match. For e.g.

# cat t.txt
first line
ind is a shortform of india

I am trying to return the word "india" because it contains the string "ind" but I do not need the exact match. I have tried this...

# grep -o 'ind' t.txt
ind
ind

Solution

Would you please try the following:

grep -Eo '[A-Za-z]+ind|ind[A-Za-z]+' t.txt

Output:

india

The regex [A-Za-z]+ind|ind[A-Za-z]+ matches ind including the preceding or following alphabets.
