linux系统使用lsof命令"-bash: lsof: command not found"
在redhat系统下想使用lsof命令查看应用端口占用情况
[root@photo720 ~]# uname -a Linux photo720 3.10.0-514.26.2.el7.x86_64 #1 SMP Tue Jul 4 15:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux [root@photo720 ~]# lsof -i:80 -bash: lsof: command not found [root@photo720 ~]# |
发现lsof命令使用不了，因为没有安装lsof
安装命令如下：
yum install -y lsof
