Question

How to use grep to search for two regex at the same time. Say, I am looking for “My name is” and “my bank account ” in a text like:

My name is Mike. I'm 16 years old.
I have no clue how to solve my grep problem,but
if I manage to solve it, then I'll transfer 
you some money from my bank account. 

I’d like grep to return:

My name is
my bank account

Is it possible to do it with just one grep call or should I write a script to do that for me?

If you do not care about a trailing newline, simply use grep:

< file.txt grep -o "My name is\|my bank account" | tr '\n' ' '

If you would prefer a trailing newline, use awk:

awk -v RS="My name is|my bank account" 'RT != "" { printf "%s ", RT } END { printf "\n" }' file.txt
