[SOLVED] How to execute a text extracted through grep and sed in bash

Issue

I am trying to execute a command based on extracting it from README file. I was able to extract it using grep and sed:

cat README.md |  grep -i "docker build" | grep -vi "dockerfile.debug" |  sed 's/.*\(d[a-z]\).*/\1/'

This script would give a result something like 'docker build .' I want to execute that command.

But I am not sure how to execute the extracted text. I thought 'exec' would work but I couldn't apply it. Please help me find a way to execute the text extracted through the above script.

Solution

Set your command in

$(CommandToExecute)

or back-ticks

`CommandToExecute`

As Example:

$(cat README.md |  grep -i "docker build" | grep -vi "dockerfile.debug" |  sed 's/.*\(d[a-z]\).*/\1/'
);
