#pidin a | grep <进程号/名称>

# pidin a | grep usb307255 io-usb-otg -t memory=/memory/ram/dma -dqcom-xhci ioport=0xa800000,irq=170,soc=8155,memory=/memory/ram/dma, -n /dev/usb2/io-usb-otg356410 usblauncher_otg -S 2 -c /etc/usblauncher/usb2.lua -M /etc/usblauncher/rules.mnt -m /var/pps -n /dev/usb2/io-usb-otg -E -e -0430143 io-hid -dusb1155112 grep usb


2.1.2 结束/杀死<进程/线程>

#slay  <进程名>

# slay io-usb-otg
#
# pidin a | grep usb356410 usblauncher_otg -S 2 -c /etc/usblauncher/usb2.lua -M /etc/usblauncher/rules.mnt -m /var/pps -n /dev/usb2/io-usb-otg -E -e -0430143 io-hid -dusb1183784 grep usb


如上图，结束进程io-usb-otg之后，再次查看进程名，已经不存在了。

#kill 

使用方法： kill [ -s signame | -signum | -signame ] {pid|job}...
                   kill -l [exit_status] 

#kill <参数> <进程PID>

配置工具：ifconfig、route、hostname、netmap
查询工具：netstat、alive

ifconfig //与Linux基本一样

# ifconfig --help
ifconfig: illegal option -- -

查看IP

# ifconfig

  如果出现status: no carrier是由于当前phy的link状态是down的，所以status是no carrier的 

netstat//与Linux基本一样

# netstat --help
netstat: illegal option -- -
usage: netstat [-Aan] [-f address_family]netstat [-bdgiLmnqrsSv] [-f address_family] [-F fib_selector]netstat [-dn] [-I interface] [-w wait]netstat [-p protocol]netstat [-p protocol] -P pcbaddrnetstat [-p protocol] [-i] [-I Interface]netstat [-s] [-f address_family] [-i] [-I Interface]netstat [-s] [-B] [-I interface]
