how to grep for a word and display only the word
Hi,
When we "grep" for a word in a file, it returns the lines containing the word that we searched for. Is there a way to display only the words and not the entire line containing them. Thanks Ananth

Using grep -o in linux, it gives the list wherever the pattern appears. The file
input_file has "Hello World Hi Hello Hello Hello Hello Bye " for eg: grep -o "Hello" input_file Hello Hello Hello Hello Hello sed -n -e "s/.*\(Hello\).*/\1/p" input_file But in using sed, it prints One Hello per line, becoz of \1. Is it any other way to print same as in linux. TIA

It would be better if you use -w option to grep.
