How can I assign the output of this command to a variable in Shell?

Question

I have the following command:

egrep -e "\\\\" pom.xml | egrep -v -e "\\\\$"

I want to assign it to a variable so that I can echo it later in this code:

egrep -e "\\\\" pom.xml | egrep -v -e "\\\\$" &> /dev/null if [ $? == 0 ]; then echo "Errors in POM were found" echo "line matches (result of the command)" fi

Be aware that, depending on your shell and the version thereof, the return value of the pipeline could be the first command or the last command. You could probably just stick a period at the end of your pattern in the first grep and have the same result. — dannysauer

POM_ERRORS=$(egrep -e "\\\\" pom.xml | egrep -v -e "\\\\$")
