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"
