Overview

Here are sample examples to do it

Let’s create a sample.txt file first

sample.txt

This file
contains word1 and
also word2

Here are some ways to search two words together using grep

Approach 1

• Use \| as a separator between two words that need to be searched

Example

some_user@macOS grep 'word1\|word2' ./sample.txt
contains word1 and
also word2

Approach 2

• Use -e for each word that needs to be searched

Example

some_user@macOS grep -e word1 -e word2 ./sample.txt
contains word1 and
also word2

Approach 3

• Use -E and |

Example

some_user@macOS grep -E 'word1|word2' ./sample.txt
contains word1 and
also word2
