如何将此命令的输出分配给Shell中的变量？
[英]How can I assign the output of this command to a variable in Shell?
问题描述
I have the following command: 
我有以下命令：
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: 我想将它分配给一个变量，以便我可以在以后的代码中回显它：
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
