从进程获取tomcat安装路径

1、变量前后截取

workdir=`ps -ef | grep "catalina.home" | grep -v "grep"`

workdir=${workdir##*catalina.home=}

workdir=${workdir%% *}

echo $workdir

2、grep+awk单行拆分转多行再拆分

ps -ef | grep "catalina.home" | grep -v "grep" | awk '{for ( i=1; i<=NF; i++) print $i}' | grep "catalina.home" | awk -F'=' '{print $2}'

附：

-sh-3.2# ps -ef | grep "catalina.home" | grep -v "grep"
