chkconfig关闭必须的5个服务或者取出第一列

chkconfig 查找出第一列,开头不包含0的

chkconfig|egrep -o "^[^0]+"|egrep -v "sshd|network|crond|sysstat"

awk取

#for i in $(chkconfig|awk     '!/sshd|network|rysslog|crond/{print $1}')
#do
#     echo    "chkconfig $i off"
#don

egep不准确,第一个准
for i in $(chkconfig|egrep -o "^[a-z]+"|egrep -v "sshd|rsyslog|network|crond|sysstat")
do
 echo "chkconfig $i off"
done

sed方法取

chkconfig|sed -rn '/sshd|network|crond|rsyslog/!s#(.*)0:.*#\1#gp'
