[SOLVED] Display X characters after matched word

Issue

I'd like to display the file and version number for different services. For example there might be a line in the text file that says nginx 1.13.0. I'd like to be able to search every single instance of nginx [0-9].[0-9].[0-9] and have it displayed with the version number and file name / line.

I've already tried this command which works well for displaying the matched files:

grep -lrEH "nginx [0-9].[0-9].[0-9]"

Solution

You are close, missing that it might be more than one digit +. You should also escape the ., so it mean only . and not any character.

Try:

grep -EHro "nginx [0-9]+\.[0-9]+\.[0-9]+"
