PowerShell（ contain ise Script tool ）
one . Operation of directories and files
1.cd（ Switch directory ）chdir
cd /d c：
cd command
/d option
c：\ parameter （ route ）
2.dir（ Display all contents under the current file , Include files , folder ）
dir /a：h express /a Properties of
Show hidden files in the current folder , folder
：h express /a Properties of
3.md （ Directory creation , You can create multiple directories at once , Parent directory does not exist ） mkdir
md c:
4.rd（ Delete directory ）
rd /s /q rd c：\zhangsan
/s Deleting a multi tier directory is mandatory
/q Quiet mode , No reminder
5.move（ move file , Rename files and directories ）
move c：\111 c：\1212 Moving from current to current is renaming
6.copy（ copy ）
copy e：\1212* c：
take e Under disk 1212 Copy all files in folder to c disc
7.xcopy（ Generally used to copy directories ）
xcopy /e Company folder e：\ Company folder
/e Copy directories using , Include empty folders
8.del（ Delete one or more files , Do not delete folder ）
del c：\ Company folder
two , Text operation （ Text document ）
1.type（ Display text content ）
type c：\3.txt Text document content only
2.> redirect （ Redirect the output of a command to a previous input file , The correct content will be entered into the file ）
ipconfig> ip.txt
3.| The Conduit （ Take the result output from the previous command as the object input later , Class filtering ）
nslookup www.baidu.com | findstr name
4.findstr（ Find string in file ）
three , Network related commands
1.ipconfig（ see TCP/IP parameter ）
TCP/IP parameter
-IP address ： Identify a host in the network （ An interface ）
- Subnet mask ： Usually with ip Simultaneous use , Used to represent the range of the network
- gateway ： Host to host interface of router ip Address of
-dns address ： Domain name resolution , Access domain name must be configured correctly DNS address
Only view ip address , Subnet mask , Default gateway
If you want to view details ipconfig /all
2.ping（ Detect network connectivity ）
3.tracert Route tracking （ Used to track how many routers the destination passes through ）
4.nslookup Domain name resolution
5.netstat View the number of connections to the host （tcp udp）
netstat -anop tcp
6.telnet Remote connection , Check whether the port of a host is open （ be confined only to tcp port ）
telnet 192.162.161.145 3389? default 23
7.route View the routing table of this machine
8. Set fixed TCP,IP parameter
ip There are generally two ways to set the address
- Static settings （static）
netsh interface ip set address “ Ethernet ” static 192.168.100.100 255.255.255.0
192.168.100.1
192.168.100.100 255.255.255.0 ip Address and subnet mask
192.168.100.1 default gateway
netsh interface ip set dnsservors “ Ethernet ” static 114.114.114.114
netsh interface ip add dnsservors “ Ethernet ” index=2 8.8.8.8
- Dynamic settings （DHCP）
netsh interface ip set address “ Ethernet ” dhcp
netsh interface ip set dnsservors “ Ethernet ” dhcp
9.arp（ Address resolution protocol ： A known ip Address resolves to MAC address ）
arp -a see arp Cache table （ Including dynamic learning and static binding ）
arp -d Empty cache table
arp -s Static binding
Access is often denied
netsh -c “i i” add neighbors 9 “192.168.19.28”“00-E1-8C-EB-3A-52”
netsh interface ip add neighbors 9 “192.168.19.28”“00-E1-8C-EB-3A-52”
