How can I grep a specific word in a single string that contains repetitions?

For example :

Apple_1 Apple_1_Test Juice_2 Juice_2_H

If I use grep -Eo 'Apple_1' I get two results (because of two Apple_1 in the original string)

But what if I want to grep only the perfect word Apple_1 and not Apple_1_Test or Juice_2 and not Juice_2_H??

Add a word boundary assertion:

grep -Eo '\bApple_1\b'
  • 4
    Option -w is enough: grep -Ewo 'Apple_1'
