Grep and regex on a file with bash

Question

in a file how could I select line where there is :

Value_1 and Name_species

I should get for instance:

Value_1:(O)_content_:Name_species

I tried

grep "Value_1:*:Name_species" file

but it does not work...

You have to add a dot `.` before the asterix like `.*` or else you are repeating the colon — The fourth bird, May 16 '19 at 14:09

The simpliest way to combine two greps is by grepping the one after the other:

grep "Value_1" <filename> | grep "Name_species"
